For engineers reviewing the UPD78F1164AGC(R)-UEU-AX datasheet, UPD78F1164AGC(R)-UEU-AX pinout, UPD78F1164AGC(R)-UEU-AX application, or UPD78F1164AGC(R)-UEU-AX equivalent, key selection criteria include Flash endurance (100,000 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 industrial firmware deployments.

Technical Context

The UPD78F1164AGC(R)-UEU-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a 12-bit successive-approximation ADC with 16 input channels and programmable sampling time, plus three 16-bit timer arrays supporting PWM, input capture, and output compare modes.

Peripheral connectivity includes two full-duplex UARTs with LIN support, one I²C bus interface with multimaster capability, and a 16-bit watchdog timer with window function. The device uses SuperFlash® technology licensed from Silicon Storage Technology for reliable Flash programming and data retention over 20 years at 85°C.

FAQ

What is the maximum operating frequency of the UPD78F1164AGC(R)-UEU-AX?

The UPD78F1164AGC(R)-UEU-AX operates at a maximum frequency of 20 MHz using its internal high-speed oscillator or an external crystal. At this speed, the 78K0R core achieves approximately 20 MIPS performance with single-cycle instruction execution for most operations. The device supports clock division and PLL bypass modes to optimize power versus performance trade-offs in the UPD78F1164AGC(R)-UEU-AX application environment.

Does the UPD78F1164AGC(R)-UEU-AX support in-system programming (ISP)?

Yes, the UPD78F1164AGC(R)-UEU-AX supports in-system programming via its single-wire on-chip debug interface using tools such as the QB-MINI2 emulator. Firmware updates can be performed without removing the device from the PCB, and the Flash memory allows up to 100,000 erase/write cycles with data retention exceeding 20 years at 85°C - a key reliability feature of the UPD78F1164AGC(R)-UEU-AX.

What analog features are integrated into the UPD78F1164AGC(R)-UEU-AX?

The UPD78F1164AGC(R)-UEU-AX integrates a 12-bit successive-approximation ADC with 16 input channels, programmable sampling time, hardware averaging (up to 32 samples), and window comparison function. It also includes an on-chip temperature sensor and dual analog reference inputs (AVREF0/AVREF1) for flexible full-scale voltage configuration - all essential for accurate sensor conditioning in the UPD78F1164AGC(R)-UEU-AX design context.

Is the UPD78F1164AGC(R)-UEU-AX pin-compatible with other members of the 78K0R/KG3 family?

The UPD78F1164AGC(R)-UEU-AX shares the same 100-pin LQFP package and core pinout with other 78K0R/KG3 devices such as the UPD78F1163A and UPD78F1165A, but functional pin assignments differ for peripheral signals (e.g., UART, timer outputs). While mechanical compatibility exists, firmware and schematic changes are required when substituting - confirming that UPD78F1164AGC(R)-UEU-AX is not a drop-in replacement without validation.

What development tools are officially supported for the UPD78F1164AGC(R)-UEU-AX?

Renesas officially supports the UPD78F1164AGC(R)-UEU-AX with the RA78K0R assembler, CC78K0R C compiler (Ver. 2.00), QB-MINI2 on-chip debug emulator, and PG-FP5 Flash programmer.
