Product details
Overview
R5F100LDDFA#V0 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, and operation from -40°C to +85°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100LDDFA#V0 datasheet, R5F100LDDFA#V0 pinout, R5F100LDDFA#V0 application, or R5F100LDDFA#V0 equivalent, key selection criteria include its 64-pin LQFP package with 26 analog input channels, integrated data flash with 1M rewrite cycles, low-power STOP/HALT/SNOOZE modes, and support for LIN-bus via UART peripherals.
Technical Context
The R5F100LDDFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports background operation during data flash rewriting and includes a dedicated low-speed on-chip oscillator for watchdog timer independence.
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, calendar-based RTC with alarm/correction, and three serial interface types (CSI, UART/LIN, I²C) with channel counts scaled per pin count - all operating across 1.6–5.5 V supply and qualified for industrial ambient (-40°C to +85°C).
