Philips moved ARM technology into catalog microcontrollers with the LPC2100 family: the first named parts were the LPC2104, LPC2105 and LPC2106, built around an ARM7TDMI-S core. The move offered developers a route from 8-bit and 16-bit controllers to 32-bit processing without giving up the familiar, low-cost microcontroller model.
What Philips announced—and what “standard end” meant
On 13 March 2002, Philips and ARM announced a common embedded-controller architecture combining the ARM7TDMI-S processor core with Philips’ 0.18-micron CMOS embedded-Flash process. Philips was extending ARM beyond custom ASIC and system-on-chip designs into standalone, catalog-style microcontrollers that customers could select for ordinary embedded products. “Standard” here describes that catalog-product approach, not a new industry standard or a promise that every device shared identical hardware.
Philips said the process enabled operation down to 1.2 V, compared with the then-current 0.25-micron, 2.5 V standard. The company also claimed faster throughput, doubled on-chip memory density, higher I/O bandwidth and lower power. Those are Philips’ claims about its process and architecture in the 2002 announcement, not independent measurements or a guarantee that every system would operate at 1.2 V.
The architecture combined a common design with ARM PrimeCell peripherals, EmbeddedICE-RT debugging and Embedded Trace Macrocell support. For product developers, shared memory mapping, interrupt handling, flash programming and debugging were intended to make devices in the family easier to approach with common tools and software.

Which LPC2100 parts came first?
EE Times reported the LPC2104, LPC2105 and LPC2106 as the initial devices for 16- and 32-bit applications. Philips Semiconductors’ 2003 product information, as reported by EE Times, gives the LPC2104’s detailed specifications below. The available figures do not establish all corresponding specifications for the LPC2105 and LPC2106.
| Part | Flash | SRAM | Core and operating frequency | Documented distinction |
|---|---|---|---|---|
| LPC2104 | 128 kB, zero-wait-state flash at 60 MHz | 16 kB | ARM7TDMI-S; 60 MHz | RTC, watchdog, PLL, PWM, I2C and SPI; 48-pin LQFP or MicroLeadFrame package. Source: EE Times reporting Philips Semiconductors, 2003. |
| LPC2105 | Not stated in the cited EE Times/Philips Semiconductors 2003 information | 32 kB | ARM7TDMI-S; 60 MHz family operating frequency | More SRAM than the LPC2104, intended to help with connectivity workloads. Source: EE Times reporting Philips Semiconductors, 2003. |
| LPC2106 | Not stated in the cited EE Times/Philips Semiconductors 2003 information | 64 kB | ARM7TDMI-S; 60 MHz family operating frequency | More SRAM than the LPC2104, intended to help with connectivity workloads. Source: EE Times reporting Philips Semiconductors, 2003. |
The three devices shared a memory map, interrupt controller, flash programming and update mechanism, peripherals and debug facilities, according to EE Times. That commonality mattered as much as the processor: teams could target different memory capacities without starting from entirely unrelated device architectures. Philips positioned the larger SRAM options for uses such as TCP/IP and other connectivity workloads.

Why Philips wanted 8-bit and 16-bit developers to move up
Philips presented the LPC2100 as a “smooth, low-cost migration path” from 8-bit and 16-bit microcontrollers to 32-bit devices. The practical appeal was more processing capability and the possibility of reusing software and development knowledge, while keeping a standard MCU form factor and approach rather than commissioning a custom chip. Migration was a product strategy, not a guarantee that an existing program would run unchanged: the core, peripherals, memory map and development setup still had to fit the application.
Contemporary coverage described planned sampling in late 2002 and volume production in early 2003, initially emphasizing automotive and dial-up networking/TCP-IP applications. The stated application range across Philips and industry coverage included automotive cabin controls, industrial and medical devices, software modems, display monitors, audio entertainment, connectivity and battery-powered consumer products. These are intended or discussed markets, not evidence that every LPC2100 device included every interface those products might need.

How the LPC2000 family expanded
Later LPC2000 derivatives added memory-rich options and CAN support, extending the family’s fit for automotive and industrial buses. EDN described the expanded line as retaining the ARM7TDMI-S core and Philips’ 0.18-micron embedded-Flash process, with operation reaching up to 60 MHz. That broad family description should not be read as a complete specification for any particular derivative; peripheral sets, memory sizes and package details vary by part and require the specific device documentation.
When comparing an LPC2000 device with another controller, check the exact core and clock, flash and SRAM capacity, voltage and power requirements, peripheral set (including CAN, ADC, USB, Ethernet or serial interfaces), package and pin count, debugging and in-system programming support, software compatibility, and present-day lifecycle status. A family name alone does not establish that a particular chip has a needed peripheral or remains available.

What development tools and boards were documented?
ARM announced a RealView Developer Kit with compilation tools, a debugger and JTAG interface support for ARM and Thumb instruction sets. Embedded Trace support was intended to shorten development cycles by giving developers more visibility into program execution.
Keil’s MCB2130 evaluation board provides a separate, concrete example of LPC2000-era hardware: it used the LPC2138 and exposed 512 kB of flash, 32 kB of RAM, timers, ADC, DAC, PWM and GPIO. It is an LPC213x board, not a board built around one of the original LPC2104/2105/2106 parts. Its listed components describe that evaluation board, not the entire MCU family.

The historical product information establishes that Philips made the LPC2104 and that Keil documented an LPC2138-based MCB2130 evaluation board. It does not establish current stock, an official replacement, or lifecycle status. Treat any present-day offer as a seller-specific listing, not proof of current manufacturer support.
Before buying a legacy MCU or board, verify the exact part number and package, seller reputation, device markings and date codes, whether the listing is for the chip or a complete board, and whether the required tools and programming interface are included. Check that the board’s target MCU and exposed peripherals match the project; an LPC213x board may be useful for ARM7 evaluation but is not interchangeable with an LPC2104 design by default.
