Overview

UPD78F1164GC(R)-UEU-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KG3 family, designed for embedded control in industrial and consumer applications. It features 128 KB on-chip Flash memory, 8 KB RAM, a 16-bit CPU core, 52 I/O pins, and integrated peripherals including UART, I²C, SPI, 12-bit ADC (8 channels), and 16-bit timer arrays. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V.

For engineers reviewing the UPD78F1164GC(R)-UEU-AX datasheet, UPD78F1164GC(R)-UEU-AX pinout, UPD78F1164GC(R)-UEU-AX application, or UPD78F1164GC(R)-UEU-AX equivalent, key selection considerations include Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +85°C), package type (LQFP-64), and compliance with industrial-grade reliability standards per Renesas' "Standard" quality grade classification.

Technical Context

The UPD78F1164GC(R)-UEU-AX implements the 78K0R CPU core with Harvard architecture, supporting 16-bit data paths and 20-bit addressing. 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 multifunction timers (each with capture/compare/PWM output), two serial interface modules (UART/I²C/SPI configurable), and a watchdog timer with independent clock source. The device supports on-chip debug via single-wire interface and flash self-programming using the built-in boot swap function.

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 clock (32 MHz but with wait states); no dedicated hardware CRC.	Better power efficiency (150 µA/MHz), smaller footprint (QFN-48), but reduced Flash/RAM and fewer timers.	Select when ultra-low power and cost sensitivity outweigh need for large code space or advanced peripherals.
MB95560PFT-G-SAMPLE	Fujitsu FM3-based; 128 KB Flash, 16 KB RAM, Cortex-M0+ core; higher interrupt latency, different toolchain.	Stronger floating-point support and richer DMA engine - better suited for audio processing or complex filtering.	Select when migrating to ARM ecosystem or requiring certified functional safety extensions (not available on UPD78F1164GC(R)-UEU-AX).

Compared with R5F100LEAFB#30 and MB95560PFT-G-SAMPLE, the UPD78F1164GC(R)-UEU-AX offers superior Flash endurance (100k vs. 30k cycles), native support for legacy 78K0R toolchains (RA78K0R/CC78K0R), and proven qualification in industrial temperature cycling - making it optimal for long-lifecycle, maintenance-free embedded controllers.

FAQ

What is the maximum operating frequency of the UPD78F1164GC(R)-UEU-AX?

The UPD78F1164GC(R)-UEU-AX operates at a maximum CPU clock frequency of 20 MHz under standard conditions (VDD = 2.7–5.5 V, TA = −40°C to +85°C). This frequency is achieved using the on-chip high-speed oscillator or an external crystal up to 20 MHz. The device does not support PLL multiplication beyond this base frequency, and timing-critical peripherals like the 12-bit ADC require clock division to maintain specified accuracy.

Does the UPD78F1164GC(R)-UEU-AX support in-system programming (ISP)?

Yes, the UPD78F1164GC(R)-UEU-AX supports in-system programming via its single-wire debug interface (SWD) using Renesas' E1 or E20 emulators. It also enables self-programming through the built-in boot swap function, allowing firmware updates without removing the chip from the board. The UPD78F1164GC(R)-UEU-AX requires FLMD0 pin configuration and proper voltage sequencing during programming mode entry.

What is the Flash memory endurance specification for the UPD78F1164GC(R)-UEU-AX?

The UPD78F1164GC(R)-UEU-AX uses SuperFlash® technology with guaranteed endurance of 100,000 write/erase cycles per block and data retention exceeding 20 years at +85°C. This specification is validated per JEDEC JESD22-A117 and applies to all 128 KB of on-chip Flash memory. Wear leveling must be implemented in firmware to distribute writes across sectors and achieve full lifecycle potential.

Is the UPD78F1164GC(R)-UEU-AX qualified for automotive applications?

No, the UPD78F1164GC(R)-UEU-AX is classified under Renesas' "Standard" quality grade, intended for industrial, consumer, and office equipment - not automotive. It lacks AEC-Q100 qualification, extended temperature screening (−40°C to +125°C), and automotive-specific failure analysis reporting. For automotive use, Renesas recommends RL78/F1x or RH850 families instead of the UPD78F1164GC(R)-UEU-AX.

How many analog-to-digital converter (ADC) channels does the UPD78F1164GC(R)-UEU-AX have?

The UPD78F1164GC(R)-UEU-AX integrates a single 12-bit successive-approximation ADC with 8 input channels (AN0–AN7), supporting both single-ended and differential measurement modes. Conversion can be triggered by software, timer overflows, or external events, and results are stored in dedicated 16-bit result registers accessible via SFRs. The ADC includes internal reference options (AVREF0/AVREF1) and supports programmable sampling time per channel.
