Product details
Overview
R7F102GCE2DLA#AC0 from Renesas is a 36-pin WFLGA-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and integrated capacitive touch sensing supporting up to 29 keys. It operates from 1.6 V to 5.5 V, delivers 37.5 µA/MHz active current and 200 nA STOP-mode current, and targets ultra-low-power industrial HMI and sensor node applications.
For engineers reviewing the R7F102GCE2DLA#AC0 datasheet, R7F102GCE2DLA#AC0 pinout, R7F102GCE2DLA#AC0 application, or R7F102GCE2DLA#AC0 equivalent, key selection criteria include its 36-pin WFLGA (4 × 4 mm, 0.50-mm pitch) footprint, -40°C to +105°C industrial temperature grade, CTSU2La capacitive touch unit, RTC with alarm, and dual I²C/Simplified I²C interfaces.
Technical Context
The RL78/G22 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing-0.03125 µs at 32 MHz (high-speed on-chip oscillator) or 30.5 µs at 32.768 kHz (subsystem clock). It integrates a SNOOZE mode sequencer (SMS) enabling CPU-free low-power periodic sensing using 32 programmable commands from a 21-instruction set.
Peripheral integration includes an Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) supporting block/chain transfers, and a 10-bit A/D converter with internal 1.48 V reference and temperature sensor. The device supports UARTA (up to 4 channels), Simplified SPI (up to 5), and I²C/Simplified I²C (up to 6 channels).

FAQ
What is the operating temperature range of the R7F102GCE2DLA#AC0?
The R7F102GCE2DLA#AC0 is rated for industrial operation from -40°C to +105°C ambient temperature. This specification is confirmed in the Renesas RL78/G22 datasheet (R01DS0424EJ0120 Rev.1.20, Page 1) and applies specifically to the "3C" industrial-grade variant denoted by the "3" in the part number's temperature field. It ensures reliable flash retention, RTC accuracy, and CTSU2La performance across this full range.
Does the R7F102GCE2DLA#AC0 include an integrated capacitive touch sensing unit?
Yes, the R7F102GCE2DLA#AC0 integrates the CTSU2La (Capacitive Touch Sensing Unit 2nd generation Low-power version), supporting up to 29 self-capacitance keys or matrix mutual-capacitance configurations. This is explicitly documented in the RL78/G22 datasheet (Page 1, "Features") and confirmed by pin functions such as TS00–TS28 across its 36-pin WFLGA package.
What is the flash memory configuration of the R7F102GCE2DLA#AC0?
The R7F102GCE2DLA#AC0 contains 32 KB of code flash memory organized in 2 KB blocks, plus 2 KB of data flash memory with background operation (BGO) support. This configuration is specified in the RL78/G22 datasheet (Page 1, "Code flash memory" and "Data flash memory" sections) and aligns with the "C" memory code in the part number (R7F102GCE… = 32 KB).
Which package type does the R7F102GCE2DLA#AC0 use?
The R7F102GCE2DLA#AC0 uses a 36-pin WFLGA (Wafer-Level Glass Array) package measuring 4 × 4 mm with 0.50-mm pitch. The "LA" in the part number and "#AC0" suffix (indicating WFLGA tray packaging) confirm this, as detailed in Table 1-1 and Section 1.3.7 of the RL78/G22 datasheet (R01DS0424EJ0120 Rev.1.20).
Does the R7F102GCE2DLA#AC0 support real-time clock functionality with calendar and alarm?
Yes, the R7F102GCE2DLA#AC0 includes a full-featured real-time clock (RTC) that supports counting from one second to 99 years, alarm interrupt generation, and clock correction. This is verified in the RL78/G22 datasheet (Page 2, "Realtime clock: 1 channel") and reflected in dedicated pins like RTC1HZ (P30) and associated registers in the user manual.
