Product details
Overview
R5F2134CXJFP#U0 from Renesas Electronics is a 16-bit R8C/27 Group single-chip microcontroller with 32 KB flash program memory, 1.5 KB RAM, and dual 1 KB data flash blocks. It features a 10-bit 12-channel ADC, hardware LIN module (using Timer RA and UART0), two UARTs, I²C interface, and real-time clock capability via Timer RE. Designed for automotive body electronics and industrial control systems operating from −40°C to +85°C.
For engineers reviewing the R5F2134CXJFP#U0 datasheet, R5F2134CXJFP#U0 pinout, R5F2134CXJFP#U0 application, or R5F2134CXJFP#U0 equivalent, key selection criteria include its J-version temperature grade (−40°C to +85°C), 32-pin LQFP package (PLQP0032GB-A), integrated LIN physical layer support, dual data flash blocks for EEPROM emulation, and low-power stop mode current of 0.7 µA at 3.0 V.
Technical Context
The R5F2134CXJFP#U0 implements the R8C CPU core with 89 fundamental instructions and executes at 50 ns minimum instruction time (20 MHz XIN, 3.0–5.5 V). Its memory architecture includes separate 1 Mbyte address space for code and data, with on-chip flash supporting 10,000 write/erase cycles for data flash and 1,000 for program ROM.
Peripheral integration centers on mixed-signal control: Timer RC provides 16-bit input capture/output compare; Timer RE delivers real-time clock and compare match functions; UART0 is tightly coupled with Timer RA to form a hardware LIN transceiver; and the 10-bit A/D converter supports simultaneous sampling across 12 analog inputs with internal reference voltage support.
