Overview
R5F12047GNA#60 from Renesas Electronics is a 16-pin, industrial-grade RL78/G15 16-bit microcontroller with 4 KB code flash, 1 KB data flash, and 1 KB RAM. It operates from 2.4 to 5.5 V, supports −40°C to +105°C ambient, and integrates an 8-channel 16-bit timer array, 7-channel 8/10-bit ADC, dual simplified I²C, UART, and CSI interfaces - deployed in smart sensor nodes requiring low-power, deterministic timing and analog signal acquisition.
For engineers reviewing the R5F12047GNA#60 datasheet, R5F12047GNA#60 pinout, R5F12047GNA#60 application, or R5F12047GNA#60 equivalent, key selection criteria include its HWQFN-16 (3 × 3 mm, 0.5-mm pitch) package, 16-MHz high-speed on-chip oscillator ±1.0% accuracy at −20°C to +85°C, 4 KB flash with self-programming, and support for STOP/HALT low-power modes.
Technical Context
The R5F12047GNA#60 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.0625 μs at 16 MHz. Its clock system combines selectable high-speed on-chip oscillator (1–16 MHz), low-speed 15-kHz on-chip oscillator, and external crystal (X1/X2) or EXCLK input up to 12 MHz.
Peripheral integration includes TAU0 timer array (8 channels), SAU0 serial array unit (2 channels supporting CSI/UART/I²C), 1-channel comparator with internal/external reference selection, and BCD correction logic. All I/O pins support interrupt capability (INTP0–INTP7), N-ch open-drain output (VDD-tolerant), and on-chip pull-up resistors.
