Product details
Overview
UPD78F1201MC-CAB-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/Ix3 family, featuring 64 KB on-chip Flash memory, 4 KB RAM, and a 20 MHz max CPU clock. It integrates UART, I²C, 10-bit ADC (8 channels), and 16-bit timer arrays for embedded control. Used in industrial sensor nodes and motor-driven appliances requiring deterministic real-time response.
For engineers reviewing the UPD78F1201MC-CAB-AX datasheet, UPD78F1201MC-CAB-AX pinout, UPD78F1201MC-CAB-AX application, or UPD78F1201MC-CAB-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating voltage range (2.7–5.5 V), and support for on-chip debug via single-wire interface - all confirmed for this exact package variant.
Technical Context
The UPD78F1201MC-CAB-AX implements the 78K0R CPU core with 16-bit ALU, 16-bit data bus, and Harvard architecture separating program and data memory spaces. It supports interrupt nesting up to 8 levels and includes a watchdog timer with independent clock source.
Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM functions), a serial array unit supporting UART/I²C/SPI modes, and an analog comparator with selectable reference. All peripherals are memory-mapped and controlled via dedicated SFRs with bit-addressable registers.

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 core, 32 KB Flash, 4 KB RAM, same 64-pin LQFP but different pin mapping and no SAU-based I²C | Lacks integrated I²C master; requires external level shifter for 5 V sensor interfaces | Select when migrating to Renesas' newer RL78 platform with lower active current (120 μA/MHz) |
| STM32F072CBT6 | ARM Cortex-M0+, 128 KB Flash, 16 KB RAM, 48 MHz max, different peripheral set (no TAU-style timer arrays) | Requires software-based PWM generation for precise motor timing; lacks built-in Flash security lock bits | Select when ARM ecosystem toolchain compatibility and USB device support are required |
Compared with UPD78F1201MC-CAB-AX, R5F100LEAFB#30 offers lower power but reduced peripheral integration, while STM32F072CBT6 provides higher performance and USB connectivity at the cost of increased code size and loss of deterministic timer hardware.

FAQ
What is the maximum operating frequency of the UPD78F1201MC-CAB-AX?
The UPD78F1201MC-CAB-AX supports a maximum CPU clock frequency of 20 MHz when operating within its specified voltage range of 2.7 V to 5.5 V. This frequency is achieved using the high-speed on-chip oscillator or an external crystal up to 20 MHz. The actual achievable frequency depends on supply voltage and ambient temperature, with derating required below 2.7 V or above 85°C ambient.
Does the UPD78F1201MC-CAB-AX support in-system programming?
Yes, the UPD78F1201MC-CAB-AX supports in-system programming (ISP) via its on-chip serial interface using the PG-FP5 programmer or compatible tools. The 64 KB Flash memory allows full firmware updates without removing the device from the PCB. Programming requires only four signals: RESET, CLK, DATA, and VDD - all accessible through standard SWD or dedicated ISP pins.
What debug interface does the UPD78F1201MC-CAB-AX provide?
The UPD78F1201MC-CAB-AX features a single-wire debug (SWD) interface compliant with Renesas' standard protocol, enabling full JTAG-equivalent functionality including breakpoints, watchpoints, and real-time register/memory access. Debugging requires only two pins (SWDIO and SWCLK) plus power and ground, and is supported by the ID78K0R-QB debugger and RA78K0R IDE toolchain.
Is the UPD78F1201MC-CAB-AX qualified for automotive applications?
No, the UPD78F1201MC-CAB-AX is rated as a Standard quality grade device per Renesas documentation and is intended for industrial, office, and consumer applications - not automotive or safety-critical systems. It does not meet AEC-Q100 requirements. For automotive use, Renesas recommends the RL78/F1x or RH850 families, which are explicitly qualified and supported with PPAP documentation.
What is the Flash memory endurance specification for the UPD78F1201MC-CAB-AX?
The UPD78F1201MC-CAB-AX guarantees 100,000 write/erase cycles for its 64 KB on-chip Flash memory under standard operating conditions (Ta = 25°C, VDD = 5.0 V). Endurance is verified per JEDEC JESD22-A117 and remains valid across the full industrial temperature range (−40°C to +85°C), with data retention exceeding 20 years at 85°C.
