Product details
Overview
UPD78F1165AGF-GAS-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 16-bit timer arrays, UART, I²C, and 10-bit ADC. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F1165AGF-GAS-AX datasheet, UPD78F1165AGF-GAS-AX pinout, UPD78F1165AGF-GAS-AX application, or UPD78F1165AGF-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 single-wire interface - all critical for cost-sensitive, long-lifecycle industrial firmware deployments.
Technical Context
The UPD78F1165AGF-GAS-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 detector (LVD) with 3 selectable thresholds and supports two power-saving modes: HALT and STOP.
Peripheral integration includes a 16-bit multifunction timer array (TAU) with capture/compare and PWM output, a 10-bit 24-channel ADC with scan mode and hardware trigger, and dual serial interfaces (UART and I²C) supporting master/slave operation and clock synchronization up to 1 MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LEAFB#30 | RL78/G13-based; 64 KB Flash, 4 KB RAM, lower max frequency (32 MHz but 1.25 DMIPS/MHz vs. 78K0R's 1.25 MIPS/MHz); no hardware ADC scan mode | Lower memory and peripheral count; suited for simpler control loops where ADC channel count ≤ 8 | Select when migrating to Renesas' newer RL78 platform with toolchain continuity and lower active power (120 µA/MHz) |
| MB95560PMT-G-SNE1 | Fujitsu FM3-based; 128 KB Flash, 16 KB RAM, 32-bit Cortex-M3 core; requires external clock source and lacks integrated LVD | Higher compute throughput but larger footprint and BOM cost; no native support for 5 V tolerant I/O | Choose when application demands floating-point math or RTOS scheduling latency < 5 µs - not for direct drop-in replacement |
Compared with UPD78F1165AGF-GAS-AX, R5F100LEAFB#30 offers modern low-power architecture but reduced analog integration, while MB95560PMT-G-SNE1 delivers higher processing headroom at the expense of 5 V compatibility and self-contained voltage monitoring - making UPD78F1165AGF-GAS-AX optimal for legacy 5 V industrial designs requiring robust mixed-signal integration.

FAQ
What is the maximum operating frequency of the UPD78F1165AGF-GAS-AX?
The UPD78F1165AGF-GAS-AX operates at a maximum CPU clock frequency of 20 MHz, delivering 1.25 MIPS per MHz. This frequency is supported across the full −40°C to +85°C industrial temperature range and 2.7–5.5 V supply voltage, with timing validated by Renesas' electrical specifications in the 78K0R/KE3 User's Manual U17854EJ9V0UD.
Does the UPD78F1165AGF-GAS-AX support in-system programming (ISP)?
Yes, the UPD78F1165AGF-GAS-AX supports in-system programming via its on-chip debug interface (OCDS) using single-wire communication. The device includes a ROM-resident bootloader enabling Flash reprogramming without removing the chip from the target board, provided the FLMD0 pin is held low during reset to enter programming mode.
What is the ADC resolution and channel count for the UPD78F1165AGF-GAS-AX?
The UPD78F1165AGF-GAS-AX features a 10-bit successive approximation ADC with 24 input channels. Its integral nonlinearity is specified at ±1 LSB, and it supports hardware-triggered scan mode that automatically sequences conversions across selected channels and stores results in dedicated RAM without CPU intervention.
Is the UPD78F1165AGF-GAS-AX pin-compatible with other 78K0R/KE3 devices?
No, the UPD78F1165AGF-GAS-AX is not pin-compatible with earlier μPD78F114x or μPD78F114xA variants due to differences in port mapping and peripheral assignment. While it shares the same 100-pin LQFP package outline, pin functions such as P120–P124 and P140/P141 differ significantly - requiring PCB layout revision for migration.
What debug tools are officially supported for the UPD78F1165AGF-GAS-AX?
Renesas officially supports the QB-MINI2 On-Chip Debug Emulator (U18371E) and ID78K0R-QB Ver. 3.20 Integrated Debugger (U17839E) for the UPD78F1165AGF-GAS-AX. These tools provide full OCDS functionality including breakpoints, memory inspection, and real-time register read/write over the single-wire debug interface.
