Overview
R5F10DSLLFB#H2G from Renesas Electronics is a 16-bit RL78/D1A microcontroller in a 128-pin LQFP package, featuring 512 KB flash memory, 32 KB RAM, and integrated CAN 2.0B controller with dual-channel support. It operates at up to 32 MHz, supports 1.8–5.5 V supply, and includes hardware real-time clock, 24-bit watchdog timer, and 12-bit ADC with 32 channels - deployed in automotive body control modules requiring functional safety-aware firmware execution.
For engineers reviewing the R5F10DSLLFB#H2G datasheet, R5F10DSLLFB#H2G pinout, R5F10DSLLFB#H2G application, or R5F10DSLLFB#H2G equivalent, key selection criteria include dual-CAN interface capability, ASIL-B-ready peripheral configuration, 128-pin LQFP thermal performance, and RL78's ultra-low-power active mode (66 μA/MHz) for battery-backed vehicle subsystems.
Technical Context
The R5F10DSLLFB#H2G implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions including multiply/divide and bit manipulation. Its memory subsystem integrates 512 KB on-chip flash with background operation (BGO), 32 KB RAM, and 8 KB data flash for EEPROM emulation.
Peripherals include two independent CAN controllers compliant with ISO 11898-1:2015, 12-bit ADC with sample-and-hold and window comparator, 16-bit timer arrays (TMR0–TMR3), serial interfaces (SCI, I²C, CSI), and a dedicated LIN master module - all synchronized via a programmable system clock generator with PLL and sub-clock oscillator support.
