Product details
Overview
R5F100BDANA#W0 from Renesas is a 32-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 32 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 industrial temperature range. It delivers 41 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (26 channels), RTC, UART, I²C, SPI, and 16-bit timers for embedded control in battery-powered and space-constrained applications.
For engineers reviewing the R5F100BDANA#W0 datasheet, R5F100BDANA#W0 pinout, R5F100BDANA#W0 application, or R5F100BDANA#W0 equivalent, key selection criteria include its 32-pin HWQFN-0.5 mm pitch package, industrial-grade temperature support, integrated data flash with background operation, low-voltage operation down to 1.6 V, and RL78 CPU core's CISC architecture with 3-stage pipeline and sub-μs instruction timing.
Technical Context
The R5F100BDANA#W0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports multiple clock sources including high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and subsystem clock for RTC.
Power management includes on-chip POR, LVD with 14 selectable voltage levels, and three ultra-low-power modes-HALT, STOP, and SNOOZE-enabling operation with only RTC and LVD active at 0.57 μA. Memory subsystem comprises 32 KB code flash (1 KB block size), 4 KB data flash supporting background operation and 1M rewrite cycles, and 2 KB on-chip RAM.
