Product details
Overview
R5F100MJAFB#30 from Renesas is an RL78/G13 8-bit microcontroller with 192 KB flash memory, 8 KB data flash, and 16 KB RAM, operating at up to 32 MHz with 41 DMIPS performance. It features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces (UART, I²C, CSI), targeting battery-powered industrial sensors and smart metering systems.
For engineers reviewing the R5F100MJAFB#30 datasheet, R5F100MJAFB#30 pinout, R5F100MJAFB#30 application, or R5F100MJAFB#30 equivalent, key selection criteria include its 80-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature grade (G), on-chip debug support, and self-programming flash with boot swap capability.
Technical Context
The R5F100MJAFB#30 implements the RL78 CPU core with a 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 ultra-low-speed mode). Its memory subsystem includes 192 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 16 KB SRAM - all accessible within a 1 MB address space.
Power management integrates a POR circuit, 14-level LVD with interrupt/reset options, and three low-power modes (HALT, STOP, SNOOZE). Peripheral integration includes dual DMA controllers (4 channels), 16-bit timers (12 channels), 12-bit interval timer, watchdog timer, and hardware multiplier/divider for 16×16/32÷32 operations.
