Product details
Overview
R5F11NMGAFB#30 from Renesas is an RL78/H1D 80-pin ultra-low-power MCU with integrated analog front-end (24-bit ΔΣ A/D, PGA, rail-to-rail op-amps, dual D/A), LCD controller/driver (36 seg × 8 com), and real-time clock 2. It delivers 33 DMIPS at 24 MHz, operates from 1.8 V to 5.5 V, and achieves 70.8 μA/MHz active current and 0.68 μA Halt mode-targeted for precision healthcare and flow metering systems.
For engineers reviewing the R5F11NMGAFB#30 datasheet, R5F11NMGAFB#30 pinout, R5F11NMGAFB#30 application, or R5F11NMGAFB#30 equivalent, key selection criteria include its 128 KB flash/5.5 KB RAM configuration, AFE channel count (ANI12–ANI14, PGA00P/N, AMP0O/N/P), LCD drive capability (SEG0–SEG35, COM0–COM7), and industrial-grade −40°C to +85°C operation in LFQFP-80 package.
Technical Context
The R5F11NMGAFB#30 implements the RL78 CISC CPU core with 3-stage pipeline, supporting multiply/divide and MAC instructions across a 1 MB address space. Its analog subsystem includes a dedicated 24-bit ΔΣ A/D converter (SNDR 85 dB, 488 sps–15.625 ksps) with programmable gain instrumentation amplifier (x1–x64), plus three operational amplifiers (AMP0–AMP2) and two D/A converters (8-bit DAC0, 12-bit DAC1).
Timing and control are managed via Timer Array Unit (TAU) with eight 16-bit channels, two 8-bit interval timers, RTC2 with calendar/alarm, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining. Power management includes HALT/STOP/SNOOZE modes, on-chip LVD (9-level selectable), POR, and dual voltage regulators (REGA for analog circuits, REGC for core).
