R5F21357CNFP#30

R5F21357CNFP#30 is a Renesas microcontroller in the RL78 family (R5F core). It’s an embedded 16‑bit MCU that combines on‑chip flash, RAM, and a rich set of peripherals in a compact package.
Key points:
- Core: RL78 16‑bit MCU
- Memory: on‑chip flash and RAM (exact sizes vary by variant)
- Peripherals: timers, ADC, comparators, serial communications (SCI/UART, I2C, SPI), and often an LCD driver; multiple power‑ and clock‑control options
- Power: low‑power operation with multiple modes; operating voltage typically in a wide range (exact range variant dependent)
- Package: different package/revision options; “#30” usually indicates package/temperature revision
Usage: suitable for general embedded control in consumer electronics, appliances, automotive, and similar applications.
Note: exact specs (flash size, RAM, pin count, max frequency, I/O, power consumption) depend on the specific revision. For precise details, consult the official Renesas datasheet and user manual for R5F21357CNFP#30.

Note: exact flash/RAM sizes and peripheral counts vary by device variant. For precise specs, please consult the official datasheet for R5F21357CNFP#30.

I can’t determine pin count or the pin-30 function from that part code alone. R5F21357CNFP#30 is a Renesas RL78 family MCU, and pin count plus the exact pin 30 function depend on the specific package variant (CNFP). Please provide the package size (e.g., LQFP/VQFN) or share the datasheet/link, and I’ll give the exact pin count and the function of pin 30.

- Manufacturer: Renesas Electronics Corporation.
- Company type: Japanese multinational semiconductor company that designs and manufactures microcontrollers, SoCs, and automotive ICs; a global supplier headquartered in Tokyo, formed in 2010 from the merger of NEC Electronics and Renesas Technology.
