Overview

UPD78F1167AGC(S)-UEU-M1-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 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.

For engineers reviewing the UPD78F1167AGC(S)-UEU-M1-AX datasheet, UPD78F1167AGC(S)-UEU-M1-AX pinout, UPD78F1167AGC(S)-UEU-M1-AX application, or UPD78F1167AGC(S)-UEU-M1-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 embedded firmware development and long-lifecycle industrial deployment.

Technical Context

The UPD78F1167AGC(S)-UEU-M1-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a 32-bit programmable watchdog timer, low-voltage detection circuit (LVD) with 4 selectable thresholds, and power-saving modes including HALT and STOP.

Peripheral integration includes a 10-bit successive-approximation ADC with sample-and-hold, dual UARTs supporting asynchronous communication with framing error detection, and an I²C bus interface compliant with standard-mode (100 kbps) and fast-mode (400 kbps) specifications - enabling direct connection to sensors, displays, and host controllers without external level-shifting.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
R5F100PLGSP	RL78/G13 core, 128 KB Flash, same 100-pin LQFP but different pinout; lacks on-chip EEPROM	Higher code efficiency (1.2x MIPS/MHz), lower active current (90 μA/MHz), but no hardware averaging in ADC	Select for new designs prioritizing ultra-low power and C compiler optimization; requires PCB redesign due to non-pin-compatible pin mapping
MB95560P	Fujitsu FM3 family, 128 KB Flash, 100-pin LQFP, 12-bit ADC (8 channels), no FINE interface	Higher ADC resolution but fewer analog inputs; uses JTAG instead of FINE for debug	Choose when 12-bit precision is mandatory and JTAG infrastructure is already deployed; not drop-in replaceable

Compared with UPD78F1167AGC(S)-UEU-M1-AX, R5F100PLGSP offers better energy efficiency and modern toolchain support but demands layout changes, while MB95560P trades ADC channel count for resolution and replaces FINE with JTAG - making both alternatives functionally comparable but not pin- or debug-interface compatible.

FAQ

What is the maximum operating frequency of the UPD78F1167AGC(S)-UEU-M1-AX?

The UPD78F1167AGC(S)-UEU-M1-AX supports a maximum CPU clock frequency of 20 MHz when using an external crystal or ceramic resonator. Its internal high-speed oscillator is factory-trimmed to ±2% accuracy at 1 MHz, and the PLL can multiply the input clock up to 20 MHz with appropriate configuration of the system clock control registers. This frequency enables real-time execution of control loops with sub-50 μs latency in typical industrial applications.

Does the UPD78F1167AGC(S)-UEU-M1-AX include hardware debug support?

Yes, the UPD78F1167AGC(S)-UEU-M1-AX features the FINE (Fast In-Circuit Emulator) interface, a 4-pin serial debug port supporting non-intrusive breakpoints, register inspection, and flash programming. Unlike JTAG, FINE requires no dedicated TCK/TMS pins and shares signals with standard I/O ports, reducing pin count overhead. Renesas provides QB-MINI2 and ID78K0R-QB tools fully compatible with UPD78F1167AGC(S)-UEU-M1-AX for production programming and field firmware updates.

What is the Flash memory endurance specification for UPD78F1167AGC(S)-UEU-M1-AX?

The UPD78F1167AGC(S)-UEU-M1-AX uses SuperFlash® technology licensed from Silicon Storage Technology, guaranteeing 100,000 write/erase cycles per sector and 20-year data retention at +85°C. Each Flash block can be erased independently, and the device includes hardware-assisted erase suspend/resume functionality. These characteristics make UPD78F1167AGC(S)-UEU-M1-AX suitable for applications requiring frequent field firmware updates or parameter logging without external EEPROM.

Can the UPD78F1167AGC(S)-UEU-M1-AX operate from a 3.3 V supply only?

Yes, the UPD78F1167AGC(S)-UEU-M1-AX operates reliably across 2.7 V to 5.5 V, so it functions correctly at 3.3 V nominal supply. Its internal voltage regulator (controlled by REGC pin) generates a stable 3.3 V core voltage regardless of input rail, and all I/Os are 5 V tolerant when configured as inputs - allowing direct interfacing with legacy 5 V peripherals without level shifters. The LVD circuit provides four programmable thresholds down to 2.5 V for graceful shutdown handling.

Is the UPD78F1167AGC(S)-UEU-M1-AX qualified for automotive applications?

No, the UPD78F1167AGC(S)-UEU-M1-AX is classified under Renesas' "Standard" quality grade, intended for industrial, office, and consumer equipment - not automotive or safety-critical systems. It meets AEC-Q100 stress test requirements only optionally upon special request and does not carry automotive qualification documentation. For automotive use, Renesas recommends RL78/F1x or RH850 families, which are explicitly qualified to AEC-Q100 Grade 2 (−40°C to +105°C) and ISO 26262 ASIL-B ready.
