Product details
Overview
R5F21354MNFP#V0 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 16 KB program flash, 1.5 KB RAM, and 4 KB data flash (1 KB × 4 blocks) supporting background operation (BGO). It operates at up to 20 MHz (VCC = 2.7–5.5 V), features 47 CMOS I/O ports with pull-up select, and integrates UART0/1/2, I²C, LIN, 10-bit × 12-channel ADC, dual 8-bit DACs, and six timer modules (RA–RE + RD dual 16-bit) for motor control and real-time clocking in consumer appliance subsystems.
For engineers reviewing the R5F21354MNFP#V0 datasheet, R5F21354MNFP#V0 pinout, R5F21354MNFP#V0 application, or R5F21354MNFP#V0 equivalent, key selection considerations include its N-version temperature range (−20°C to +85°C), 52-pin LQFP package (PLQP0052JA-A), integrated LIN hardware module, BGO-capable data flash, and low-power stop mode (2.0 µA @ 3.0 V).
Technical Context
The R5F21354MNFP#V0 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte (00000h–FFFFFh), with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash at 03000h–03FFFh.
It supports four clock sources: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - with selectable dividers (1/2/4/8/16) and oscillation stop detection. Power modes include standard, wait (3.5 µA @ 32 kHz), and stop (2.0 µA), all enabled via software-controlled register settings.
