Product details
Overview
R5F2135CMNFP#50 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 128 KB flash program memory, 10 KB RAM, and 4 KB data flash (1 KB × 4 blocks) supporting background operation (BGO). It integrates UART0/1/2, I²C-bus, LIN hardware module, 10-bit ADC (12 channels), dual 8-bit DACs, comparators, and six timer units (RA–RE + dual RD) for motor control and real-time signal processing in consumer appliance control systems.
For engineers reviewing the R5F2135CMNFP#50 datasheet, R5F2135CMNFP#50 pinout, R5F2135CMNFP#50 application, or R5F2135CMNFP#50 equivalent, this MCU delivers deterministic real-time response via 69 interrupt vectors, 7-level priority nesting, and low-power wait/stop modes - critical for battery-backed timers, appliance UI subsystems, and embedded motor drive firmware development.
Technical Context
The R5F2135CMNFP#50 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its 1 Mbyte address space supports single-chip mode execution at up to 20 MHz (50 ns min instruction time) under 2.7–5.5 V supply.
It features four independent clock sources: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - enabling flexible power/performance trade-offs across operating, wait, and stop modes with typical current draw of 6.5 mA (5 V/20 MHz) and 2.0 µA (stop mode).
