Overview
R5F21358MDFP#50 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 64 KB flash program ROM, 6 KB RAM, and 4 KB data flash (1 KB × 4 blocks) supporting background operation (BGO). It delivers 50 ns minimum instruction execution at 20 MHz (VCC = 2.7–5.5 V), integrates dual 8-bit timers (RA/RB), dual 16-bit timers (RC/RD), real-time clock (RE), 10-bit × 12-channel ADC, dual 8-bit DACs, LIN hardware module, and I²C/UART/SSU serial interfaces - deployed in consumer audio equipment control subsystems.
For engineers reviewing the R5F21358MDFP#50 datasheet, R5F21358MDFP#50 pinout, R5F21358MDFP#50 application, or R5F21358MDFP#50 equivalent, key selection criteria include its -40°C to +85°C industrial temperature rating (D version), 52-pin LQFP package (PLQP0052JA-A), on-chip debug support, and integrated voltage detection with programmable reset levels.
Technical Context
The R5F21358MDFP#50 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte address space, and a dedicated 16×16→32-bit multiplier with multiply-accumulate capability. Its memory architecture separates 64 KB program ROM (08000h–0BFFFh), 6 KB RAM (00400h–01BFFh), and 4 KB data flash (03000h–03FFFh), all accessible via unified addressing.
Peripheral integration includes three UART channels (UART0/1/2), one I²C bus (shared with SSU), hardware LIN (using timer RA and UART0), 12-channel 10-bit ADC with sample-and-hold and sweep mode, two 8-bit DAC outputs (DA0/DA1), and four independent timer modules (RA–RD) supporting PWM, input capture, and complementary three-phase waveform generation.
