Product details
Overview
UPD78F1166AGF(R)-GAS-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KG3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated peripherals including 10-bit ADC (16 channels), UART, CSI, I²C, and 16-bit timer arrays. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial equipment and consumer appliances.
For engineers reviewing the UPD78F1166AGF(R)-GAS-AX datasheet, UPD78F1166AGF(R)-GAS-AX pinout, UPD78F1166AGF(R)-GAS-AX application, or UPD78F1166AGF(R)-GAS-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 designs.
Technical Context
The UPD78F1166AGF(R)-GAS-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory structure, and instruction set compatible with earlier 78K0 devices. It integrates a 3-channel 16-bit timer array with capture/compare and PWM output capability, plus dual 10-bit ADC units with simultaneous sampling control.
Its peripheral set includes two UARTs (one with LIN support), one CSI interface, one I²C bus interface, and a watchdog timer with independent clock source. The device supports low-power modes (HALT, STOP) with wake-up via external interrupt or peripheral event, enabling energy-efficient operation in battery-backed systems.
Key Specifications

Pinout & Package
The UPD78F1166AGF(R)-GAS-AX is housed in an 80-pin LQFP (12 mm × 12 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are defined across 8 general-purpose ports (P0–P8), 3 special-function ports (P11, P12, P13), and dedicated analog/digital power and control pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P06 | Port 0 bidirectional I/O | Configurable as general-purpose digital I/O or alternate function pins (e.g., UART0 TX/RX, CSI0 clock/data) - enables flexible peripheral mapping. |
| P10–P17 | Port 1 bidirectional I/O | Supports timer array channel outputs (TO0–TO7), ADC trigger inputs, and external interrupt sources - critical for time-critical event handling. |
| P40–P47 | Port 4 bidirectional I/O | Includes I²C SDA/SCL, UART1 TX/RX, and LIN transceiver control - simplifies communication subsystem integration. |
| AVREF0/AVREF1 | Analog reference inputs | Accept external reference voltages (up to VDD) for ADC - improves measurement accuracy when using precision external references. |
| RESET | Active-low reset input | Asynchronous hardware reset with internal pull-up - ensures reliable initialization under brown-out or ESD transient conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFB#30 | RL78/G13-based; 64 KB Flash, 4 KB RAM, lower max clock (32 MHz but with 1.25 DMIPS/MHz vs. 78K0R's 0.9 DMIPS/MHz) | Targets newer RL78 ecosystem with enhanced low-power features but lacks dual ADC simultaneous sampling | Choose for migration path to Renesas' newer platform with toolchain continuity, not for identical feature parity. |
| MB95F572KPMC-GSE1 | Fujitsu FM3-based; 128 KB Flash, 12 KB RAM, 48 MHz max, but no native LIN or FINE debug | Offers higher performance and larger RAM but requires external debug probe and lacks LIN physical layer support | Prefer where raw throughput matters more than automotive protocol integration or debug simplicity. |

FAQ
What is the maximum operating frequency of the UPD78F1166AGF(R)-GAS-AX?
The UPD78F1166AGF(R)-GAS-AX operates at a maximum frequency of 20 MHz when powered within its specified 2.7–5.5 V supply range. This clock speed is derived from the internal high-speed oscillator or external crystal input, and it directly determines instruction execution rate and peripheral timing resolution. The UPD78F1166AGF(R)-GAS-AX maintains full functionality-including ADC conversion, timer operations, and serial communication-at this rated frequency under industrial temperature conditions.
Does the UPD78F1166AGF(R)-GAS-AX support in-system programming (ISP)?
Yes, the UPD78F1166AGF(R)-GAS-AX supports in-system programming via its on-chip FINE debug interface, allowing firmware updates without removing the device from the PCB. Programming is performed using Renesas' PG-FP5 programmer or compatible tools, and the 128 KB Flash memory is rated for 100,000 erase/write cycles. The UPD78F1166AGF(R)-GAS-AX also includes read-out protection and flash lock bits to safeguard intellectual property during field deployment.
What analog peripherals are integrated into the UPD78F1166AGF(R)-GAS-AX?
The UPD78F1166AGF(R)-GAS-AX integrates two independent 10-bit successive approximation ADC units, supporting up to 16 input channels with programmable sampling time and simultaneous conversion capability. It also includes dedicated analog reference pins (AVREF0/AVREF1), analog ground (AVSS), and internal voltage regulator control (REGC) for stable analog domain operation. These peripherals enable precise sensor signal conditioning without external ADC components in the UPD78F1166AGF(R)-GAS-AX design.
Is the UPD78F1166AGF(R)-GAS-AX pin-compatible with other members of the 78K0R/KG3 family?
The UPD78F1166AGF(R)-GAS-AX shares the same 80-pin LQFP package and core pinout with other 78K0R/KG3 devices such as UPD78F1165AGF(R)-GAS-AX and UPD78F1167AGF(R)-GAS-AX, but functional pin assignments differ based on Flash size, RAM allocation, and peripheral enablement. While mechanical mounting is identical, register-level initialization and peripheral configuration must be verified per device datasheet. The UPD78F1166AGF(R)-GAS-AX is not a drop-in replacement for variants with different ADC channel counts or timer array configurations.
What development tools are officially supported for the UPD78F1166AGF(R)-GAS-AX?
Renesas officially supports the UPD78F1166AGF(R)-GAS-AX with the CC78K0R C compiler, RA78K0R assembler, SM+ system simulator, and ID78K0R-QB integrated debugger. Hardware tools include the QB-MINI2 on-chip debug emulator and PG-FP5 flash programmer. All tools are documented in User's Manual U17894EJ9V0UD and require version compatibility with the 78K0R/KG3 series - the UPD78F1166AGF(R)-GAS-AX is not supported by RL78 or RX-series toolchains.
