Product details
Overview
R5F101GCANA#40 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory, 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, integrates 16-bit timers (12 channels), 10-bit ADC (24 channels), UART/SPI/I²C interfaces, RTC, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F101GCANA#40 datasheet, R5F101GCANA#40 pinout, R5F101GCANA#40 application, or R5F101GCANA#40 equivalent, key selection criteria include its 40-pin HWQFN-6×6mm package, absence of on-chip data flash, industrial-grade temperature support, and compatibility with Renesas' RL78 toolchain and E2 studio for low-power embedded control in space-constrained designs.
Technical Context
The R5F101GCANA#40 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It includes dedicated peripherals for real-time control: 12-channel 16-bit timer array, calendar-based RTC with alarm and correction, and background operation-capable serial interfaces (CSI, UART/LIN, I²C).
Power management is centered on HALT, STOP, and SNOOZE modes, with on-chip POR and LVD (14 selectable voltage levels). The device lacks data flash but supports self-programming of code flash with boot swap and flash shield window functions, enabling secure firmware updates without external memory.
Key Specifications
