Product details

Overview

UPD78F0501AMC-CAB-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/Kx2 family, featuring 64 KB on-chip Flash memory, 4 KB RAM, and a 16-bit CPU core operating at up to 20 MHz. It integrates UART, I²C, 10-bit ADC (8 channels), 16-bit timer arrays, and supports 5 V operation with industrial temperature range (−40°C to +85°C). It is used in motor control subsystems for HVAC blowers and appliance power management.

For engineers reviewing the UPD78F0501AMC-CAB-AX datasheet, UPD78F0501AMC-CAB-AX pinout, UPD78F0501AMC-CAB-AX application, or UPD78F0501AMC-CAB-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), A/D conversion time (1.2 μs typical), reset behavior under brownout, and compatibility with RA78K0 assembler toolchain and QB-MINI2 debug emulator.

Technical Context

The UPD78F0501AMC-CAB-AX implements the 78K0 CPU core with 16-bit ALU and 8-bit data bus, executing instructions in 1–4 clock cycles. Its on-chip peripherals include a 16-bit multifunction timer (TM00–TM03) with capture/compare/PWM output, a serial interface controller supporting UART and I²C modes, and a 10-bit successive-approximation ADC with internal reference and sample-and-hold.

It uses a 64-pin LQFP package with dedicated EVDD/EVSS pins for analog domain isolation, separate REGC pin for internal regulator control, and FLMD0 pin to select boot mode. The device supports two flash rewrite modes-standard and expanded-specification-with this variant conforming to expanded-specification timing for faster A/D conversion (1.2 μs) and tighter X1 oscillator stability (±0.5% at 4–10 MHz).

Equivalent & Alternatives

The following parts are listed as comparable options for similar 8-bit microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
R5F100PLGSP#30	RL78/G13 core; 32 KB Flash, 4 KB RAM; lower power (125 μA/MHz), but no integrated data flash.	Lacks on-chip EEPROM emulation area; requires external serial EEPROM for parameter storage.	Preferred for battery-powered nodes where ultra-low active/sleep current outweighs need for embedded data storage.
UPD78F0502MC-CAB-AX	Same 78K0/Kx2 family; 96 KB Flash, identical peripherals and pinout; higher memory density only.	Direct drop-in replacement when >64 KB code space required; same PCB layout and firmware binary compatibility.	Select when future firmware expansion or bootloader partitioning demands additional Flash capacity without hardware redesign.

Compared with UPD78F0501AMC-CAB-AX, R5F100PLGSP#30 offers superior energy efficiency but removes integrated data flash, increasing BOM cost and firmware complexity; UPD78F0502MC-CAB-AX provides seamless Flash scalability while preserving all timing, peripheral, and thermal characteristics of the original design.

FAQ

What is the maximum operating frequency of the UPD78F0501AMC-CAB-AX?

The UPD78F0501AMC-CAB-AX supports a maximum system clock frequency of 20 MHz. This is achieved using either an external crystal (X1) in the 4–10 MHz range with ±0.5% tolerance or the internal high-speed oscillator. The CPU core executes instructions in 1–4 clock cycles, enabling deterministic real-time response critical for motor control loops and sensor sampling. All timing specifications-including ADC conversion, timer resolution, and UART baud generation-are validated at this maximum frequency.

Does the UPD78F0501AMC-CAB-AX include on-chip EEPROM or data flash?

Yes, the UPD78F0501AMC-CAB-AX includes 256 bytes of on-chip data flash within its 64 KB main Flash memory array. This area is specifically designated for EEPROM emulation and can be rewritten independently using Renesas' certified self-programming library. Unlike external EEPROM, it requires no additional I²C/SPI interface or external power supply, simplifying design and improving reliability in harsh environments where UPD78F0501AMC-CAB-AX is deployed.

What development tools are officially supported for the UPD78F0501AMC-CAB-AX?

Renesas officially supports the QB-MINI2 on-chip debug emulator with programming function and the RA78K0 Ver.4.01 assembler package for the UPD78F0501AMC-CAB-AX. The QB-MINI2 provides full JTAG-based debugging, flash programming, and real-time trace capabilities. Development is further enabled by the CC78K0 C compiler Ver.4.00 and ID78K0-QB integrated debugger. All tools are validated against the UPD78F0501AMC-CAB-AX silicon revision and referenced in Renesas document U18371E and U17199E.

How does the UPD78F0501AMC-CAB-AX handle power supply brownout conditions?

The UPD78F0501AMC-CAB-AX features a built-in voltage detector with programmable threshold (2.7 V, 3.0 V, or 3.5 V) that asserts the RESET signal asynchronously when VDD falls below the selected level. Brownout detection is enabled by default after power-on and includes hysteresis to prevent oscillation during slow voltage recovery. This ensures deterministic reset behavior without external supervisory ICs-critical for safety-critical applications like appliance power management where UPD78F0501AMC-CAB-AX serves as the primary controller.

Is the UPD78F0501AMC-CAB-AX pin-compatible with other members of the 78K0/Kx2 family?

The UPD78F0501AMC-CAB-AX is pin-compatible with other 64-pin LQFP variants in the 78K0/KB2 subgroup-including UPD78F0500AMC-CAB-AX, UPD78F0502MC-CAB-AX, and UPD78F0503AMC-CAB-AX-within the same package footprint and pin assignment. However, functional differences exist: UPD78F0502MC-CAB-AX offers 96 KB Flash but identical peripherals, while UPD78F0500AMC-CAB-AX has reduced Flash (48 KB) and fewer timer channels. Pin compatibility does not guarantee full firmware or timing equivalence across all variants.
