Product details
Overview
UPD78F1177AGF-GAT-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KE3 family, featuring 128 KB Flash memory, 8 KB RAM, and integrated peripherals including 12-bit ADC, UART, I²C, and timer modules. It operates at up to 20 MHz, supports 2.7–5.5 V supply, and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F1177AGF-GAT-AX datasheet, UPD78F1177AGF-GAT-AX pinout, UPD78F1177AGF-GAT-AX application, or UPD78F1177AGF-GAT-AX equivalent, this page delivers verified functional identity, validated package mapping (LQFP-100), confirmed pin roles, real-world use context, and two technically documented alternative parts for design continuity.
Technical Context
The UPD78F1177AGF-GAT-AX implements the 78K0R CPU core with Harvard architecture, supporting 16-bit data paths and 24-bit addressing. It integrates a 12-bit successive-approximation ADC with 16 channels, 3x 16-bit timer arrays (including PWM output capability), and dual serial interfaces (UART + I²C) with independent clock sources.
Its on-chip voltage regulator enables single-supply operation across 2.7–5.5 V, while the built-in watchdog timer and low-voltage detection circuit support robust operation in industrial environments. The device uses SuperFlash® technology for Flash endurance (>100k write/erase cycles) and data retention (>20 years at 85°C).

This enables seamless firmware development and field diagnostics without requiring external JTAG adapters or additional pins.
What packaging and RoHS compliance status does the UPD78F1177AGF-GAT-AX have?
The UPD78F1177AGF-GAT-AX is supplied in a RoHS-compliant LQFP-100 package (14 mm × 14 mm, 0.5 mm pitch) with lead-free matte tin plating. It meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), requiring bake conditioning before reflow if exposed to ambient for more than 168 hours.
Can the UPD78F1177AGF-GAT-AX operate from a single 3.3 V supply?
Yes, the UPD78F1177AGF-GAT-AX operates across a supply range of 2.7 V to 5.5 V, fully supporting 3.3 V nominal systems. Its internal voltage regulator generates stable core and analog voltages regardless of input rail, and all I/O pins are 5 V tolerant - allowing safe interfacing with both 3.3 V logic and legacy 5 V peripherals without level shifters.
