Product details
Overview
R5F2L387CDFA#V0 from Renesas is an 8-bit R8C/L38C Group microcontroller featuring the R8C CPU core, 48 KB program flash, 6 KB RAM, and integrated LCD driver supporting up to 48 segment outputs and 8 common outputs. It operates at up to 20 MHz (50 ns min. instruction time), includes a 16×16-bit hardware multiplier, 10-bit ×16-channel ADC, dual 8-bit DACs, and supports -40°C to +85°C industrial temperature range in 80-pin LQFP package. Used in LCD-based consumer appliances requiring low EMI and background data flash rewriting.
For engineers reviewing the R5F2L387CDFA#V0 datasheet, R5F2L387CDFA#V0 pinout, R5F2L387CDFA#V0 application, or R5F2L387CDFA#V0 equivalent, key selection criteria include its 16-channel ADC resolution, LCD segment drive capability, D-version temperature rating, BGO-enabled data flash, and compatibility with Renesas' R8C toolchain and debug interfaces.
Technical Context
The R5F2L387CDFA#V0 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient signal processing. Its memory architecture includes 48 KB on-chip flash (1,000 write/erase cycles) and 1 KB ×4 data flash blocks with Background Operation (BGO) support for concurrent code execution and flash updates.
Peripheral integration centers on mixed-signal control: Timer RD provides three-phase complementary PWM for motor control; UART0/1/2 plus I²C and LIN modules enable multi-protocol communication; and the LCD controller integrates voltage multiplier and bias regulation for static/1/2/1/3/1/4 duty operation - all optimized for low-power, noise-immune operation in appliance front panels.
