Product details
Overview
UPD78F1178AGF-GAT-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KE3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated peripherals including 12-bit ADC (16 channels), UART, I²C, and 16-bit timer arrays. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets industrial control and sensor interface applications requiring deterministic real-time response.
For engineers reviewing the UPD78F1178AGF-GAT-AX datasheet, UPD78F1178AGF-GAT-AX pinout, UPD78F1178AGF-GAT-AX application, or UPD78F1178AGF-GAT-AX equivalent, key selection considerations include its 100-pin LQFP package, 12-bit ADC resolution with hardware averaging, dual UART support with LIN-compliant mode, and built-in low-voltage detection circuitry for robust operation in variable-power environments.
Technical Context
The UPD78F1178AGF-GAT-AX implements the 78K0R CPU core with 16-bit architecture, supporting both 8-bit and 16-bit instructions and featuring a 3-stage pipeline for efficient execution. Its memory subsystem includes 128 KB Flash with block erase capability, 8 KB RAM, and 1 KB data flash for parameter storage - all accessible via unified addressing space with mirror areas for flexible boot configuration.
Peripheral integration follows the 78K0R/KE3 architecture: the 12-bit ADC supports simultaneous sampling across multiple channels with programmable conversion timing; the 16-bit timer array provides input capture, output compare, PWM generation, and interval timing functions; and the serial interface units support asynchronous UART, synchronous CSI, and multi-master I²C protocols with automatic address recognition.

The UPD78F1178AGF-GAT-AX supports both flash programming and emulation modes through the same interface.
What ADC features does the UPD78F1178AGF-GAT-AX provide?
The UPD78F1178AGF-GAT-AX includes a 12-bit successive approximation ADC with 16 input channels, programmable sample-and-hold timing, and hardware averaging across up to 16 conversions. It supports simultaneous sampling on multiple channels using internal trigger sources such as timers or external events. The UPD78F1178AGF-GAT-AX ADC also features selectable reference voltages (internal 2.5 V or external AVREF) and automatic channel scanning with interrupt-on-complete capability.
Is the UPD78F1178AGF-GAT-AX pin-compatible with other 78K0R/KE3 devices?
Yes, the UPD78F1178AGF-GAT-AX shares the same 100-pin LQFP package and pin assignment with other members of the 78K0R/KE3 family, including UPD78F1154AGF-GAT-AX and UPD78F1146AGF-GAT-AX. This enables direct PCB reuse across variants differing only in Flash/RAM size or peripheral enablement. The UPD78F1178AGF-GAT-AX maintains identical power, ground, reset, and clock pin locations - simplifying design migration and inventory consolidation.
What is the qualified operating temperature range for the UPD78F1178AGF-GAT-AX?
The UPD78F1178AGF-GAT-AX is qualified for industrial temperature operation from −40 °C to +85 °C. This rating applies to the full electrical specification, including Flash write/erase endurance, ADC accuracy, and timing parameters. As a Standard-grade Renesas product, the UPD78F1178AGF-GAT-AX is intended for applications such as factory automation, building controls, and consumer appliances - not for automotive or safety-critical medical use without additional qualification.
