Product details
Overview
R5F100EAANA#U0 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V across –40°C to +85°C. It delivers 41 DMIPS at 32 MHz, integrates a 10-bit 26-channel ADC, real-time clock, and ultra-low-power modes (0.57 μA in RTC+LVD mode), targeting battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F100EAANA#U0 datasheet, R5F100EAANA#U0 pinout, R5F100EAANA#U0 application, or R5F100EAANA#U0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, integrated data flash with 1M rewrite cycles, dual UART/LIN support, and verified operation in consumer-grade ambient conditions (–40°C to +85°C).
Technical Context
The R5F100EAANA#U0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory architecture includes separate code flash (64 KB, 1 KB block size) and data flash (4 KB, background operation enabled), both accessible via on-chip debug and self-programming with boot swap.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock with alarm and correction, two to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) channels - all configurable under the same low-power execution framework.
Key Specifications
