Description

R5F21257SNFP#X6 is a Renesas microcontroller part number from the R5F family. It denotes a specific MCU with on‑chip flash and RAM and a set of embedded peripherals for control tasks. The “SNFP” part encodes the package type, while “#X6” encodes variant/voltage/temperature specifics. Exact details (CPU core type, clock speed, flash/RAM sizes, peripherals such as timers, ADCs, serial interfaces, and packaging) vary by revision.
For precise information, consult the official Renesas datasheet and product page for R5F21257SNFP#X6. If you’d like, I can fetch the exact specs and summarize the key parameters.

Features

R5F21257SNFP#X6 is a Renesas RL78 16-bit MCU. Key features include:
- 16-bit RL78 CPU core, up to about 32 MHz
- On-chip memory: up to 128 KB flash and up to several KB RAM (typical)
- Analog peripherals: multiple-channel 12-bit ADC and analog comparator
- Timers and PWM: several 8/16-bit timers with PWM channels
- Serial interfaces: UART/USART, I2C, SPI
- Data transfer: DTC (DMA-like) for peripheral data moves
- Clocking: internal high-speed oscillator plus external crystal support
- Power/low‑power: operate from 1.6 to 3.6 V; low-power modes with RAM retention
- Debug/Programming: in-system programming and on-chip debugging
