Product details
Overview
R5F100ECGNA#20 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), deployed in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F100ECGNA#20 datasheet, R5F100ECGNA#20 pinout, R5F100ECGNA#20 application, or R5F100ECGNA#20 equivalent, key selection criteria include its integrated 10-bit 26-channel ADC, real-time clock with calendar/alarm, LIN-capable UARTs, and hardware DMA supporting background data flash rewriting - all within a 6 × 6 mm, 0.5-mm-pitch thermally enhanced package.
Technical Context
The R5F100ECGNA#20 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, 16-bit timers (12 channels), and a dedicated watchdog timer operating on a low-speed on-chip oscillator.
Its memory subsystem includes 64 KB code flash (1 KB block size, security-protected erase/write), 4 KB data flash with background operation (BGO) and 1M-cycle endurance, and 4 KB on-chip RAM. Power management features HALT, STOP, and SNOOZE modes, plus an on-chip LVD with 14 selectable voltage thresholds and POR circuit.
