Product details
Overview
UPD78F1167AGC(S)-UEU-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, I²C, and timer arrays. 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-driven appliances.
For engineers reviewing the UPD78F1167AGC(S)-UEU-AX datasheet, UPD78F1167AGC(S)-UEU-AX pinout, UPD78F1167AGC(S)-UEU-AX application, or UPD78F1167AGC(S)-UEU-AX equivalent, key selection considerations 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 UPD78F1167AGC(S)-UEU-AX implements the 78K0R CPU core with 16-bit ALU, 32-bit accumulator support, and Harvard architecture memory mapping. It integrates a 10-bit successive-approximation ADC with sample-and-hold and programmable conversion start triggers from timer or external pin.
Peripheral coordination is managed through an interrupt controller supporting 128 vector entries, priority levels, and nested interrupts. Clock generation includes on-chip oscillator (1–20 MHz), sub-clock (32.768 kHz), and PLL options - enabling precise timing for serial communication (UART baud rates ±0.5% accuracy) and PWM motor control (16-bit resolution, dead-time insertion).
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLGFB#30 | Same 78K0R core, 96 KB Flash, 6 KB RAM, identical 100-pin LQFP package - differs in ADC channel count (12 vs. 16) and lacks SNOOZE low-power mode. | Suitable for simpler sensor nodes where fewer analog inputs and higher standby current (<5 µA) are acceptable. | Select when BOM cost reduction is prioritized over ADC channel density and ultra-low-power operation. |
| MB95560PFT-G-SNE1 | Fujitsu FM3 family part with Cortex-M0+ core, 128 KB Flash, but requires external crystal for full-speed operation and lacks on-chip SWD debug. | Better suited for applications needing ARM ecosystem tooling but less tolerant of single-chip integration constraints. | Choose only if existing design uses ARM-based middleware or requires certified functional safety libraries not available for 78K0R. |
Compared with R5F100PLGFB#30 and MB95560PFT-G-SNE1, the UPD78F1167AGC(S)-UEU-AX delivers superior analog integration (16-channel ADC), lower active power (1.8 mA/MHz), and production-ready debug infrastructure - making it optimal for cost-constrained, analog-intensive industrial controllers requiring long-term supply stability.
