Product details
Overview
UPD78F1164AGC-UEU-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KE3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated peripherals including 12-bit ADC, 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 embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F1164AGC-UEU-AX datasheet, UPD78F1164AGC-UEU-AX pinout, UPD78F1164AGC-UEU-AX application, or UPD78F1164AGC-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 confirmed for this exact part number.
Technical Context
The UPD78F1164AGC-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 12-bit successive-approximation ADC with 16 input channels and programmable sampling timing.
Peripheral subsystems include three 16-bit timer arrays (each supporting capture/compare/PWM), two UART channels with LIN support, one I²C bus interface, and a watchdog timer with independent clock source. All peripherals are memory-mapped and controlled via dedicated SFRs validated for this variant.

Pinout & Package
UPD78F1164AGC-UEU-AX is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions follow Renesas 78K0R/KE3 standard layout, including dedicated ports P0–P7, P12–P14, analog inputs (AN0–AN15), power pins (VDD/EVDD, VSS/EVSS), and debug interface (RES, FLMD0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P06 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions including UART0 TX/RX, timer output, and external interrupt inputs |
| P10–P17 | Port 1 bidirectional I/O | Supports I²C SDA/SCL, UART1 TX/RX, and ADC trigger signals; includes pull-up/pull-down control |
| AN0–AN15 | Analog input channels | 16 dedicated pins mapped to 12-bit ADC; share physical pins with P40–P43, P50–P55, P120–P124, P140–P141 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10PLGAFP#V0 | RL78/G13 core; 128 KB Flash, 12 KB RAM; lower active current (125 μA/MHz); no on-chip DAC | Better suited for ultra-low-power battery-operated nodes; lacks hardware LIN support present in UPD78F1164AGC-UEU-AX | Select when energy efficiency dominates over legacy peripheral compatibility |
| MB9BF506RPMC-G-S2 | ARM Cortex-M3 core; 512 KB Flash, 64 KB RAM; higher performance (100 MHz); different toolchain and debug interface | Targeted at complex motion control requiring floating-point math and RTOS; requires PCB redesign due to 144-pin LQFP vs. 100-pin | Select when scaling beyond 78K0R's 20 MHz throughput is required |
Compared with R5F10PLGAFP#V0 and MB9BF506RPMC-G-S2, the UPD78F1164AGC-UEU-AX delivers optimal balance of proven industrial peripheral integration (LIN, robust ADC timing), mature toolchain support (CC78K0R/RA78K0R), and pin-compatible upgrade path within the 78K0R/KE3 family - critical for sustaining long-lifecycle industrial designs.

FAQ
What is the maximum operating frequency of the UPD78F1164AGC-UEU-AX?
The UPD78F1164AGC-UEU-AX supports a maximum system clock frequency of 20 MHz when using the internal high-speed oscillator with PLL multiplication. This allows the 78K0R CPU core to execute instructions at peak throughput while maintaining timing compliance for all on-chip peripherals including the 12-bit ADC and UART modules. The UPD78F1164AGC-UEU-AX datasheet confirms this rating under the specified 2.7–5.5 V supply and −40°C to +85°C ambient conditions.
Does the UPD78F1164AGC-UEU-AX support in-system programming (ISP)?
Yes, the UPD78F1164AGC-UEU-AX supports in-application programming (IAP) via its on-chip Flash memory controller, enabling firmware updates without removing the device from the target board. Programming is performed through the single-wire debug interface or via UART using Renesas' standard Flash programming protocol. The UPD78F1164AGC-UEU-AX requires no external high-voltage supply - all operations use the standard VDD rail (2.7–5.5 V).
What debug interface does the UPD78F1164AGC-UEU-AX use?
The UPD78F1164AGC-UEU-AX uses a single-wire debug (SWD) interface compliant with Renesas' standard debug protocol for 78K0R devices. It supports full breakpoint, watchpoint, and real-time memory inspection capabilities using tools such as the E2 emulator or QB-MINI2. Unlike JTAG, SWD requires only two pins (RESET and SWDIO), simplifying PCB layout and reducing debug connector footprint for the UPD78F1164AGC-UEU-AX.
Is the UPD78F1164AGC-UEU-AX qualified for automotive applications?
No, the UPD78F1164AGC-UEU-AX is rated for Standard quality grade per Renesas documentation, targeting industrial equipment, office automation, and consumer appliances. It is not AEC-Q100 qualified and lacks the extended temperature range (−40°C to +125°C), enhanced ESD immunity, or automotive-specific qualification testing required for automotive use. For automotive alternatives, Renesas offers the RL78/F1x or RH850 families - not the UPD78F1164AGC-UEU-AX.
What is the Flash endurance specification for the UPD78F1164AGC-UEU-AX?
The UPD78F1164AGC-UEU-AX guarantees 100,000 write/erase cycles for its 128 KB on-chip Flash memory, as specified in Renesas' 78K0R/KE3 datasheet and confirmed in the U17854EJ9V0UD User's Manual. This endurance applies to both block erase and page write operations and is validated across the full operating temperature range (−40°C to +85°C). Wear leveling must be implemented in firmware if exceeding cycle limits is anticipated in the UPD78F1164AGC-UEU-AX application.
