Overview
R5F1214AGSP#70 from Renesas Electronics is a 16-pin, industrial-grade RL78/G16 microcontroller featuring a 16 KB flash memory, 2 KB RAM, and integrated capacitive touch sensing unit (CTSU) with 15 channels. It operates from 2.4–5.5 V, supports ultra-low-power STOP/HALT modes, and delivers real-time clock, 16-bit timers, 10-bit ADC (11-channel), and multiple serial interfaces - deployed in smart appliance control panels requiring robust HMI and low-power operation.
For engineers reviewing the R5F1214AGSP#70 datasheet, R5F1214AGSP#70 pinout, R5F1214AGSP#70 application, or R5F1214AGSP#70 equivalent, key selection criteria include its 16-pin SSOP package, −40°C to +105°C industrial temperature rating, CTSU-based touch interface capability, and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F1214AGSP#70 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times ranging from 0.0625 μs (16 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its on-chip peripherals include a 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, and real-time clock with 99-year calendar and alarm function.
It integrates a 10-bit A/D converter with internal reference voltage (0.815 V), temperature sensor, and selectable analog inputs across 11 channels. The capacitive touch sensing unit supports both self-capacitance (up to 15 keys) and mutual capacitance (up to 16 keys in matrix configuration), with dedicated TSCAP pin and hardware-accelerated noise immunity.
