Product details
Overview
R5F1214AGSP#30 from Renesas Electronics is a 16-pin, 32 KB flash, 2 KB RAM RL78/G16 16-bit microcontroller with integrated capacitive touch sensing (15-channel CTSU), 10-bit A/D converter (11 channels), and dual serial interfaces (UART + simplified I²C). It operates from 2.4–5.5 V and supports industrial temperature range (−40°C to +105°C), targeting low-power HMI control in appliance panels and industrial sensors.
For engineers reviewing the R5F1214AGSP#30 datasheet, R5F1214AGSP#30 pinout, R5F1214AGSP#30 application, or R5F1214AGSP#30 equivalent, key selection criteria include its 16-pin SSOP package, 32 KB code flash with self-programming, 10-bit ADC with internal reference, RTC with calendar function, and hardware CTSU supporting up to 16 keys in mutual-capacitance mode.
Technical Context
The R5F1214AGSP#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling instruction execution times from 0.0625 μs (16 MHz high-speed on-chip oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates a dedicated low-speed on-chip oscillator for watchdog and RTC operation independent of main clock domain.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one watchdog timer, one real-time clock (99-year calendar, alarm, correction), and a 15-channel capacitive touch sensing unit (CTSU) supporting both self- and mutual-capacitance configurations - all managed via memory-mapped registers and interrupt-driven event handling.
