Product details
Overview
R5F104GLANA#20 from Renesas is a 48-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 128 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40°C to +105°C (industrial G-grade), delivering 44 DMIPS at 32 MHz for low-power industrial control, sensor hubs, and appliance motor management.
For engineers reviewing the R5F104GLANA#20 datasheet, R5F104GLANA#20 pinout, R5F104GLANA#20 application, or R5F104GLANA#20 equivalent, key selection criteria include its 128 KB code flash size, 12 KB RAM, 8 KB data flash with 1M rewrite cycles, 10-bit A/D converter (20-channel), and integrated real-time clock with calendar function - all within a 7 × 7 mm 0.5 mm pitch package.
Technical Context
The R5F104GLANA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a Data Transfer Controller (DTC) supporting chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral event routing without CPU intervention.
Its power architecture includes HALT, STOP, and SNOOZE modes, achieving 66 μA/MHz active current and 0.60 μA RTC+LVD retention current. The on-chip high-accuracy oscillator supports ±1.0% stability across 1.8–5.5 V and -20 to +85°C, with selectable frequencies from 1 to 64 MHz.
