Product details
Overview
UPD78F0578MC-CAB-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KB2-L family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and a 20 MHz max CPU clock. It integrates a 10-bit ADC (16 channels), UART, I²C, and 16-bit timer arrays, targeting embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F0578MC-CAB-AX datasheet, UPD78F0578MC-CAB-AX pinout, UPD78F0578MC-CAB-AX application, or UPD78F0578MC-CAB-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating voltage range (2.7–5.5 V), and support for low-power stop modes with wake-up via external interrupt or RTC alarm.
Technical Context
The UPD78F0578MC-CAB-AX implements the 78K0S CPU core with 16-bit address space and 8-bit data path, executing instructions at up to 20 MHz using internal high-speed oscillator or external crystal (1–20 MHz). Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM output), a watchdog timer with independent clock source, and a real-time clock with calendar function.
Memory architecture comprises 128 KB of on-chip Flash (organized in 1 KB blocks), 8 KB of RAM (including 256 B of data flash for EEPROM emulation), and dedicated SFR space. Boot operation supports user-defined reset vector and secure boot options via ROM-based bootloader configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LEAFB#30 | RL78/G13 core, 64 KB Flash, 4 KB RAM, lower max frequency (32 MHz @ 1.8–5.5 V); integrated LIN transceiver. | Better suited for automotive body electronics requiring LIN compliance; lacks hardware RTC and data flash. | Select when LIN bus integration is mandatory and RTC functionality is handled externally. |
| UPD78F0537GC-GAD-AX | Same 78K0/KB2-L family, 64 KB Flash, 4 KB RAM, identical pinout and peripheral set except reduced ADC channels (8 vs. 16). | Cost-optimized variant for simpler sensor systems where fewer analog inputs are required. | Choose for BOM cost reduction when full 16-channel ADC capacity is unnecessary. |

FAQ
What is the maximum operating frequency of the UPD78F0578MC-CAB-AX?
The UPD78F0578MC-CAB-AX operates at a maximum CPU frequency of 20 MHz across its full supply voltage range (2.7–5.5 V). This frequency is achievable using either the internal high-speed oscillator or an external crystal connected to X1/X2 pins. The device's instruction execution timing is fully characterized at this speed, enabling deterministic real-time response for control applications.
Does the UPD78F0578MC-CAB-AX include on-chip debug capability?
Yes, the UPD78F0578MC-CAB-AX supports on-chip debugging via the single-wire debug interface compatible with Renesas QB-MINI2 and ID78K0-QB tools. This allows full visibility into registers, memory, and program flow during development without requiring additional hardware probes or modifying the target PCB layout.
What type of Flash memory technology is used in the UPD78F0578MC-CAB-AX?
The UPD78F0578MC-CAB-AX uses Renesas' proprietary SuperFlash® technology licensed from Silicon Storage Technology, Inc., delivering 128 KB of on-chip Flash with guaranteed 100,000 write/erase cycles and 20-year data retention at 85°C. This enables reliable field firmware updates and parameter storage in harsh environments.
Can the UPD78F0578MC-CAB-AX operate from a 3.3 V supply?
Yes, the UPD78F0578MC-CAB-AX is fully specified to operate from 2.7 V to 5.5 V, making it compatible with standard 3.3 V system rails. All I/O pins are 5 V tolerant when configured as inputs, and internal regulators maintain stable core voltage regardless of supply variation within this range.
Is there hardware support for real-time clock functionality in the UPD78F0578MC-CAB-AX?
Yes, the UPD78F0578MC-CAB-AX includes a dedicated real-time clock (RTC) module with calendar function (year/month/day/hour/min/sec) and alarm interrupt capability. It operates independently from the main CPU clock and can run from a 32.768 kHz crystal or internal sub-clock, enabling accurate timekeeping during low-power stop modes.
