It operates from 1.6 V to 5.5 V and supports industrial temperature range (−40°C to +105°C) in LFQFP-80 package, targeting battery-powered sensor nodes and smart metering systems.
For engineers reviewing the R5F101MKAFB#30 datasheet, R5F101MKAFB#30 pinout, R5F101MKAFB#30 application, or R5F101MKAFB#30 equivalent, key selection criteria include its 384 KB code flash with self-programming, 20 KB RAM for real-time control stacks, 66 μA/MHz active power consumption, and hardware RTC with calendar/alarm-critical for time-stamped edge sensing and low-duty-cycle telemetry.
Technical Context
The R5F101MKAFB#30 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 ultra-low-speed mode). It integrates a 12-bit interval timer, 16-bit timers (12 channels), and a dedicated RTC with calendar function and clock correction.
Its memory subsystem includes 384 KB on-chip code flash (1 KB block size, security-protected erase/write), 8 KB data flash with background operation (BGO) and 1M rewrite cycles, and 20 KB SRAM-including flash library RAM allocation at FAF00H.
