Renesas UPD78F1167AGC(R)-UEU-AX

Overview

UPD78F1167AGC(R)-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 12-bit ADC (8 channels), 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 UPD78F1167AGC(R)-UEU-AX datasheet, UPD78F1167AGC(R)-UEU-AX pinout, UPD78F1167AGC(R)-UEU-AX application, or UPD78F1167AGC(R)-UEU-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), operating temperature range (−40°C to +85°C), and compliance with industrial-grade reliability standards per Renesas' "Standard" quality grade classification.

Technical Context

The UPD78F1167AGC(R)-UEU-AX implements the 78K0R CPU core with 16-bit architecture, supporting both 8- and 16-bit instructions. It integrates a 12-bit successive-approximation ADC with sample-and-hold, programmable gain amplifier input options, and hardware-triggered conversion via timer or external event.

Its peripheral set includes three 16-bit timer arrays (each with capture/compare, PWM, and one-shot modes), two serial interface controllers (UART and I²C), and a watchdog timer with independent clock source. Memory protection is enforced via ROM guard and RAM guard functions to prevent unintended overwrites.

Key Specifications

Pinout & Package

UPD78F1167AGC(R)-UEU-AX is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow Renesas' standardized 78K0R/KG3 pinout layout, supporting dual power domains (EVDD0/EVSS0 for analog, VDD/VSS for digital) and dedicated reset, clock, and debug interface pins.

FAQ

What is the maximum operating frequency of the UPD78F1167AGC(R)-UEU-AX?

The UPD78F1167AGC(R)-UEU-AX operates at a maximum system clock frequency of 20 MHz. This is achieved using an external crystal oscillator (up to 20 MHz) or internal high-speed RC oscillator (16 MHz typical). The 78K0R CPU core executes instructions at one cycle per instruction for most operations, enabling deterministic real-time response in control loops and communication stacks.

Does the UPD78F1167AGC(R)-UEU-AX support in-circuit debugging?

Yes, the UPD78F1167AGC(R)-UEU-AX supports full in-circuit debugging via the on-chip debug interface using Renesas' QB-MINI2 emulator. It provides non-intrusive breakpoints, real-time register and memory inspection, and flash programming through the dedicated debug pins (BKGD, RESN, and VPP). Debug functionality remains active even when the internal voltage regulator (REGC) is enabled.

What is the Flash memory endurance specification for the UPD78F1167AGC(R)-UEU-AX?

The UPD78F1167AGC(R)-UEU-AX features 128 KB of on-chip SuperFlash® memory rated for 100,000 write/erase cycles and guaranteed 10-year data retention at +85°C. This endurance level supports field firmware updates in industrial equipment without requiring external nonvolatile memory, and is validated per Renesas' qualification standards for Standard-grade products.

How does the UPD78F1167AGC(R)-UEU-AX handle analog reference voltage selection?

UPD78F1167AGC(R)-UEU-AX supports flexible analog reference configuration via AVREF0 and AVREF1 pins. Users may apply an external reference (1.0–5.5 V), use the internal 2.5 V bandgap reference, or configure AVREF0 as output of the internal reference while AVREF1 serves as ADC input. This allows calibrated ratiometric or absolute measurements depending on sensor interface requirements.

Is the UPD78F1167AGC(R)-UEU-AX qualified for automotive applications?

No, the UPD78F1167AGC(R)-UEU-AX is classified under Renesas' "Standard" quality grade, intended for industrial, office, and consumer applications - not automotive. It is not AEC-Q100 qualified, lacks extended temperature screening (−40°C to +125°C), and does not meet automotive-specific failure rate or ESD immunity requirements. For automotive use, consider Renesas' RL78/F1x or RH850 families instead.
