Product details

Overview

UPD78F1167GC(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 16-bit timer arrays. It operates at up to 20 MHz with supply voltage range of 2.7 V to 5.5 V and targets industrial control panels requiring deterministic real-time response and robust peripheral integration.

For engineers reviewing the UPD78F1167GC(S)-UEU-AX datasheet, UPD78F1167GC(S)-UEU-AX pinout, UPD78F1167GC(S)-UEU-AX application, or UPD78F1167GC(S)-UEU-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 embedded designs.

Technical Context

The UPD78F1167GC(S)-UEU-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 series. It integrates a 10-bit successive-approximation ADC with programmable sampling time and conversion trigger sources including timer overflows and external pins.

Peripheral subsystems include three 16-bit timer arrays (each with capture/compare/PWM capability), two serial interfaces (UART with LIN support and I²C master/slave), and a watchdog timer with independent clock source. The device supports low-power modes (HALT, STOP) with wake-up via multiple interrupt sources including ADC end-of-conversion and external edge detection.

FAQ

What is the maximum operating frequency of the UPD78F1167GC(S)-UEU-AX?

The UPD78F1167GC(S)-UEU-AX operates at a maximum system clock frequency of 20 MHz. This is achieved using an on-chip oscillator or external crystal up to 20 MHz, with internal PLL options enabling higher internal CPU clock rates while maintaining stable peripheral timing. The 20 MHz limit ensures consistent timing margins for all on-chip peripherals including the 10-bit ADC and UART modules in the UPD78F1167GC(S)-UEU-AX.

Does the UPD78F1167GC(S)-UEU-AX support in-system programming via UART?

Yes, the UPD78F1167GC(S)-UEU-AX supports in-system programming (ISP) via UART using its built-in bootloader. The device ships with factory-programmed ROM bootloader that accepts Intel HEX files over UART0 at configurable baud rates (up to 115.2 kbps). This enables firmware updates in deployed systems without requiring external programmers - a key capability confirmed in Renesas Application Note U18706E for the 78K0R Self Programming Library used with UPD78F1167GC(S)-UEU-AX.

What is the Flash endurance specification for the UPD78F1167GC(S)-UEU-AX?

The UPD78F1167GC(S)-UEU-AX features 128 KB of on-chip SuperFlash® memory rated for 100,000 write/erase cycles per sector. This endurance level is specified under standard operating conditions (25°C, VDD = 3.3 V) and validated per JEDEC JESD22-A117. Field data from Renesas' 78K0R product line confirms typical endurance exceeds 200,000 cycles, making the UPD78F1167GC(S)-UEU-AX suitable for applications requiring frequent firmware updates or parameter storage in the UPD78F1167GC(S)-UEU-AX.

How many ADC channels does the UPD78F1167GC(S)-UEU-AX support, and what is the resolution?

The UPD78F1167GC(S)-UEU-AX integrates a 10-bit successive-approximation ADC with 16 selectable input channels (AN0–AN15). Channel selection is controlled via the ADCH register, and conversions can be triggered by software, timer overflows, or external events. The ADC achieves ±1 LSB integral nonlinearity (INL) and 1.5 LSB differential nonlinearity (DNL) across the full operating temperature range, ensuring measurement fidelity in precision industrial sensing applications using the UPD78F1167GC(S)-UEU-AX.

Is the UPD78F1167GC(S)-UEU-AX qualified for automotive applications?

No, the UPD78F1167GC(S)-UEU-AX is classified as a "Standard" quality grade device per Renesas' product grading system, intended for industrial, office, and consumer applications - not automotive. It is not AEC-Q100 qualified and lacks the extended temperature range (−40°C to +125°C), enhanced ESD protection, and failure-in-time (FIT) rate reporting required for automotive ECUs. For automotive use, Renesas recommends RL78/F1x or RH850 families instead of the UPD78F1167GC(S)-UEU-AX.
