Product details
Overview
R5F104BCANA#V0 from Renesas is a 32-pin LFQFP-packaged RL78/G14 16-bit microcontroller with 16 KB flash, 2.5 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V at -40 to +85°C (A-grade), delivering 44 DMIPS at 32 MHz while consuming only 66 μA/MHz in active mode and 0.60 μA in RTC+LVD-only STOP mode - used in battery-powered sensor nodes and low-power industrial control interfaces.
For engineers reviewing the R5F104BCANA#V0 datasheet, R5F104BCANA#V0 pinout, R5F104BCANA#V0 application, or R5F104BCANA#V0 equivalent, this page provides verified functional specifications, package-confirmed pin roles, real-world use scenarios, and two validated alternative parts for design flexibility in cost-sensitive, ultra-low-power embedded systems.
Technical Context
The R5F104BCANA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a 10-bit A/D converter with up to 20 analog inputs, dual UART/LIN channels, and hardware event linking via ELC for deterministic peripheral coordination.
Its power management includes HALT, STOP, and SNOOZE modes with on-chip POR and LVD (14 selectable voltage thresholds), enabling robust operation across wide supply ranges. The device supports background data flash rewriting (BGO) with 1 million write cycles and operates with ±1.0% oscillator accuracy over temperature and voltage.
