Product details
Overview
R5F100BCANA#00 from Renesas Electronics is a 32-pin, 16-bit RL78/G13 microcontroller with 16 KB flash memory, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V across -40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), and integrates 10-bit ADC (6 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100BCANA#00 datasheet, R5F100BCANA#00 pinout, R5F100BCANA#00 application, or R5F100BCANA#00 equivalent, key selection criteria include its HWQFN-32 package, integrated data flash with 1M rewrite cycles, SNOOZE mode for low-latency peripheral wake-up, and support for LIN-bus communication via UART.
Technical Context
The R5F100BCANA#00 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory architecture includes separate code flash (16 KB), data flash (4 KB), and RAM (2 KB), all accessible within a 1 MB address space.
Power management includes HALT, STOP, and SNOOZE modes; on-chip peripherals comprise an 8-channel 16-bit timer, 1-channel 12-bit interval timer, 1-channel real-time clock with calendar/alarm, and a watchdog timer driven by a dedicated low-speed oscillator - enabling deterministic timing control in resource-constrained embedded systems.
