Product details
Overview
UPD78F0573MC-CAB-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KB2-L family, featuring 64 KB on-chip Flash memory, 4 KB RAM, and a 16-bit timer with capture/compare functionality. It operates at up to 20 MHz, supports 5 V operation, and integrates UART, I²C, and 10-bit ADC for embedded control in industrial sensors and motor drives.
For engineers reviewing the UPD78F0573MC-CAB-AX datasheet, UPD78F0573MC-CAB-AX pinout, UPD78F0573MC-CAB-AX application, or UPD78F0573MC-CAB-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), operating temperature range (−40°C to +85°C), and compatibility with RA78K0 assembler and CC78K0 C compiler toolchains.
Technical Context
The UPD78F0573MC-CAB-AX implements the 78K0 CPU core with 16-bit ALU, 16-level hardware stack, and instruction set compatible with earlier 78K0 devices. It uses SuperFlash® technology for program memory, enabling fast erase (≤10 ms per block) and single-byte programming.
Its clock system supports multiple sources: external crystal (1–20 MHz), ceramic resonator, or internal high-speed oscillator (8 MHz ±2%). The device includes a voltage regulator (REGC pin) for stable internal supply and supports low-power modes including HALT and STOP with wake-up via external interrupt or timer event.

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-based; 32 KB Flash, 4 KB RAM, 1.8–5.5 V operation | Better low-voltage support and lower active current (120 μA/MHz), but lacks REGC regulator pin | Select when battery-powered operation or wider supply range is required |
| UPD78F0567MC-CAB-AX | Same 78K0/KB2-L family; 48 KB Flash, identical peripheral set and pinout | Lower memory capacity suits cost-sensitive designs where firmware size ≤40 KB | Drop-in alternative if application firmware fits within 48 KB and BOM cost reduction is prioritized |
Compared with UPD78F0573MC-CAB-AX, R5F100LEAFB#30 offers superior energy efficiency but requires PCB layout changes due to different pin mapping and missing REGC functionality; UPD78F0567MC-CAB-AX shares identical packaging and peripheral configuration, enabling direct substitution where Flash capacity permits.

FAQ
What is the maximum operating frequency of the UPD78F0573MC-CAB-AX?
The UPD78F0573MC-CAB-AX operates at a maximum frequency of 20 MHz when supplied with 5 V. This speed is achievable using the external crystal oscillator (X1/XT1) or internal high-speed oscillator. At lower voltages (e.g., 4.0 V), the guaranteed maximum frequency reduces to 16 MHz per Renesas Electrical Specifications. The UPD78F0573MC-CAB-AX includes clock dividers and prescalers to support flexible peripheral timing without compromising CPU performance.
Does the UPD78F0573MC-CAB-AX support in-system programming?
Yes, the UPD78F0573MC-CAB-AX supports full in-system programming (ISP) via its on-chip debug interface using the QB-MINI2 emulator or PG-FP5 programmer. Firmware updates can be performed without removing the device from the target board. The UPD78F0573MC-CAB-AX implements a boot swap mechanism that allows safe field updates by validating new code before committing to main Flash - critical for maintaining operational continuity in deployed equipment.
What development tools are officially supported for the UPD78F0573MC-CAB-AX?
Renesas officially supports the RA78K0 assembler (Ver. 4.01), CC78K0 C compiler (Ver. 4.00), ID78K0-QB integrated debugger, and PM+ IDE for the UPD78F0573MC-CAB-AX. These tools are validated against the 78K0/KB2-L hardware specification and provide full register-aware debugging, Flash programming, and peripheral simulation. The UPD78F0573MC-CAB-AX also works with third-party tools compliant with Renesas' debug protocol, but only the listed Renesas tools guarantee full feature coverage and technical support.
Is the UPD78F0573MC-CAB-AX qualified for industrial temperature operation?
Yes, the UPD78F0573MC-CAB-AX is rated for industrial temperature operation from −40°C to +85°C. This qualification is confirmed in Renesas' official datasheets and applies to all electrical specifications, including Flash write/erase endurance, ADC accuracy, and timer jitter. The UPD78F0573MC-CAB-AX uses standard "Standard" quality grade packaging, making it suitable for factory automation, motor drives, and building control systems per Renesas' Quality Grade classification.
How does the REGC pin function on the UPD78F0573MC-CAB-AX?
The REGC pin on the UPD78F0573MC-CAB-AX connects to an external 1 μF ceramic capacitor to stabilize the internal voltage regulator that supplies the CPU core. This regulator generates a clean 3.3 V reference independent of the main 5 V VDD rail, improving noise immunity and timing stability. The UPD78F0573MC-CAB-AX requires this capacitor for reliable operation above 10 MHz; omitting it may cause intermittent resets or Flash corruption during programming sequences.
