Product details
Overview
UPD78F1203MC-CAB-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/Ix3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and a maximum operating frequency of 20 MHz. It integrates a 10-bit ADC with 16 channels, UART, I²C, and timer peripherals, and targets embedded control applications in industrial equipment and consumer appliances.
For engineers reviewing the UPD78F1203MC-CAB-AX datasheet, UPD78F1203MC-CAB-AX pinout, UPD78F1203MC-CAB-AX application, or UPD78F1203MC-CAB-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), operating voltage range (2.7–5.5 V), and support for low-power modes including HALT and STOP - all critical for battery-powered and thermally constrained designs.
Technical Context
The UPD78F1203MC-CAB-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K devices. It supports both internal high-speed oscillator (20 MHz) and external crystal (up to 20 MHz), with programmable PLL for clock scaling.
On-chip peripherals include a 16-bit multifunction timer array (MTU), watchdog timer (WDT), power-on reset (POR), and voltage detection circuit (VDET). The device uses SuperFlash® technology for Flash memory, enabling single-cycle read access and page erase capability.

FAQ
What is the maximum operating frequency of the UPD78F1203MC-CAB-AX?
The UPD78F1203MC-CAB-AX operates at a maximum system clock frequency of 20 MHz, delivering up to 16 million instructions per second (MIPS) using its 78K0R CPU core. This frequency is supported by both the internal high-speed oscillator and external crystal or ceramic resonator inputs, with optional PLL multiplication for flexible clock tree design in the UPD78F1203MC-CAB-AX.
Does the UPD78F1203MC-CAB-AX support in-system programming?
Yes, the UPD78F1203MC-CAB-AX supports in-system programming (ISP) via its on-chip debug interface using a single-wire SWD-compatible protocol. This allows full Flash memory erase, program, and verify operations without removing the device from the target board - essential for field firmware updates and production programming of the UPD78F1203MC-CAB-AX.
What is the Flash endurance specification for the UPD78F1203MC-CAB-AX?
The UPD78F1203MC-CAB-AX features 128 KB of on-chip SuperFlash® memory rated for 100,000 write/erase cycles per block. This endurance level ensures reliable operation over the full product lifetime in applications requiring frequent parameter storage or firmware updates - a key reliability metric confirmed in Renesas' official datasheet for the UPD78F1203MC-CAB-AX.
Which development tools are officially supported for the UPD78F1203MC-CAB-AX?
Renesas officially supports the QB-MINI2 on-chip debug emulator and the ID78K0R-QB integrated debugger for the UPD78F1203MC-CAB-AX. Software toolchain includes the CC78K0R C compiler and RA78K0R assembler, both validated for full register-level debugging, flash programming, and real-time trace of the UPD78F1203MC-CAB-AX.
Is the UPD78F1203MC-CAB-AX qualified for automotive applications?
No, the UPD78F1203MC-CAB-AX is classified as a Standard quality grade device per Renesas' documentation and is intended for industrial, office, and consumer applications - not automotive or safety-critical systems. For automotive-grade alternatives, Renesas offers RL78/F13 or RH850 families; the UPD78F1203MC-CAB-AX does not meet AEC-Q100 requirements.
