Overview
R5F2135AMNFP#X4 from Renesas is a 16-bit R8C CPU core MCU with 96 KB flash program ROM, 8 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), integrates 12-channel 10-bit ADC, dual 8-bit DACs, LIN hardware module, and six timer units (RA–RE + RD dual-channel), targeting embedded control in consumer audio and office equipment.
For engineers reviewing the R5F2135AMNFP#X4 datasheet, R5F2135AMNFP#X4 pinout, R5F2135AMNFP#X4 application, or R5F2135AMNFP#X4 equivalent, key selection criteria include its 52-pin LQFP package, -20°C to +85°C temperature grade (N version), integrated LIN transceiver support via UART0+TimerRA, BGO-enabled data flash for firmware updates, and low-power stop mode (2.0 µA).
Technical Context
The R5F2135AMNFP#X4 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 FFDCh–FFFFh and data flash at 03000h–03FFFh.
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 - with selectable dividers (1/2/4/8/16) and oscillation stop detection.
