Some SuperH microcontrollers are specified for 80 MHz operation, but 80 MHz is not a family-wide specification. Renesas documents it for SH-2 devices in the SH708x group, including the SH7083 and SH7084, and gives the SH7058 as another 80 MHz example. The cited SH7083 and SH7084 part records are marked obsolete, so these are best approached as legacy-device specifications—not as confirmation of current stock or a recommendation for a new design.
What SuperH is—and what 80 MHz means
SuperH is a family of embedded controller cores and products, not one microcontroller with a single clock rate. Renesas identifies branches including SH-1, SH-2, SH2-DSP and SH-2A; its historical family overview also covers later SH-3, SH-4 and SH-4A generations. The 80 MHz figure applies to particular device specifications, not every SuperH member.
Renesas’s historical overview gives 60 MHz for SH-3 and 400 MHz for SH-4A. Those are examples from different family generations, not results from a controlled performance comparison. Clock frequency alone does not establish how quickly a controller will execute a particular application.
Renesas SuperH family overview
Which SuperH microcontrollers are documented at 80 MHz?
| Device or example | Core and stated frequency | Memory details in the cited source | Lifecycle or qualification |
|---|---|---|---|
| DS70830AN80BGV (SH7083) | SuperH SH-2; maximum operating frequency 80 MHz | Not stated on the cited part record | Renesas marks the part record obsolete. Product data accessed 2026-10-04. |
| DF70844AD80FPV#ZB (SH7084) | SuperH SH-2; maximum operating frequency 80 MHz | 256 KB program memory and 16 KB RAM | Renesas marks the part record obsolete. Product data accessed 2026-10-04. |
| SH7058 | Renesas educational material describes it as an 80 MHz microcomputer for engine control | Not stated in the cited educational material | Historical educational example; the source does not establish current availability. |
The SH7083 product description says, “The SH708x provide large-capacity, high-speed on-chip flash memory capable of constant single cycle access at 80Mhz.” This is Renesas’s wording for the SH708x group; it should not be read as a specification for the entire SuperH family.

What to check before choosing or sourcing one
A maximum operating frequency is only one device attribute. Before using a SuperH part in an existing design or considering a replacement, compare the exact part numbers against the requirements of the application.

- ESP32C3supermini expansion board to provide users with a better power supply solution, the expansion board has a total of VCC1, VCC2 two power supply. Default VCC1, VCC2 output voltage is 3.3V, when you need to output a higher voltage, you can short the PCB, at this time, VCC1, VCC2 output voltage is the power supply voltage 3.7 V. Default factory is the use of the 0R resistor connected to the 3.3V, if you need to output 3.7V, remove the 0R resistor directly to the three pads shorted with tin.VCC1, VCC1, VCC2 respectively control the voltage output, need to be used to take one, which one can be dealt with.
- Core and instruction requirements: confirm the core branch and that the firmware, compiler and required instructions are compatible.
- Memory and peripherals: check program memory, RAM and required peripheral features against the exact part record and hardware manual.
- Electrical and timing limits: consult the applicable hardware manual for supply voltage, temperature range, clock configuration, timing and peripheral details. Do not infer these from the frequency headline.
- Package and pinout: verify the full manufacturer part number, package and pin count against the board design.
- Lifecycle and stock: distinguish manufacturer lifecycle status from seller inventory. An obsolete record does not prove that no stock remains, and a listing does not establish that a part is new, genuine or suitable.
For the cited obsolete examples, verify the exact suffix, package, condition and seller stock before treating a listing as available. Renesas’s educational material also lists a SuperH-family C/C++ compiler package and a family real-time operating system; the cited pages do not establish present availability, target compatibility or commercial terms, so confirm those directly before planning maintenance work.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is SuperH a starting point for a new design?
For SH7616 specifically, Renesas says support is limited to customers who have already adopted the group and recommends RX or RZ families for new designs. That guidance is about SH7616; it should not be treated as a blanket lifecycle statement about every SuperH product. Check lifecycle status and current manufacturer recommendations for the exact device under consideration.
