Product details
Overview
UPD78F1176AGF(S)-GAT-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KH3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated peripherals including 10-bit ADC (16 channels), UART, I²C, and 16-bit timer arrays. It operates at up to 20 MHz with supply voltage range of 2.7–5.5 V and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F1176AGF(S)-GAT-AX datasheet, UPD78F1176AGF(S)-GAT-AX pinout, UPD78F1176AGF(S)-GAT-AX application, or UPD78F1176AGF(S)-GAT-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +85°C), and support for on-chip debug via FINE interface - all critical for cost-sensitive, long-lifecycle industrial firmware deployments.
Technical Context
The UPD78F1176AGF(S)-GAT-AX implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and Harvard architecture separating program and data memory. It integrates a programmable low-voltage detection (LVD) circuit with 3 selectable thresholds (2.7 V, 3.3 V, 4.2 V) and supports two power-saving modes: HALT and STOP.
Peripheral integration includes a 16-bit multifunction timer (TM00–TM03) with input capture, output compare, and PWM generation; a 10-bit successive approximation ADC with internal reference (1.45 V) and scan mode; and dual serial interfaces (UART ch0/ch1 and I²C bus interface) sharing dedicated pins with port functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10PLGKSP#V0 | Same 78K0R core, identical pinout, but with 96 KB Flash and no internal LVD circuit | Lacks programmable voltage monitor - requires external supervisor IC for brown-out protection | Select when Flash size margin allows and external LVD is acceptable to reduce component count |
| UPD78F1175AGF(S)-GAT-AX | Direct predecessor with 96 KB Flash, same peripheral set, and identical package/pinout | Lower Flash capacity limits complex bootloader or dual-bank OTA update implementation | Choose for legacy design migration where code size remains under 96 KB and no new feature dependencies exist |
Compared with UPD78F1176AGF(S)-GAT-AX, R5F10PLGKSP#V0 trades integrated LVD for reduced cost and smaller die, while UPD78F1175AGF(S)-GAT-AX offers proven compatibility at the expense of future firmware scalability - both require validation of Flash wear leveling and debug interface timing against target PCB layout.
