Product details
Overview
UPD78F0101HMC-5A4-A from Renesas Electronics is an 8-bit Flash-based microcontroller in the 78K0/KB1+ family, featuring 16 KB on-chip Flash memory, 1 KB RAM, a 16 MHz max CPU clock, and integrated peripherals including 8-channel 10-bit ADC, UART, I²C, and 16-bit timer/counters. It operates from a single 2.7–5.5 V supply and targets embedded control in industrial sensors and appliance motor interfaces.
For engineers reviewing the UPD78F0101HMC-5A4-A datasheet, UPD78F0101HMC-5A4-A pinout, UPD78F0101HMC-5A4-A application, or UPD78F0101HMC-5A4-A equivalent, key selection considerations include its 48-pin LQFP package, self-programmable Flash with option byte configuration, 2.1 V power-on reset threshold, and support for on-chip debug via QB-78K0MINI emulator.
Technical Context
The UPD78F0101HMC-5A4-A implements the 78K0 CPU core with 16-bit address space and supports both internal high-speed oscillator (16 MHz) and external crystal (1–20 MHz) clock sources. Its interrupt system includes 22 vectored sources with 4 priority levels, enabling deterministic real-time response in closed-loop control.
On-chip peripherals include a 10-bit ADC with sample-and-hold and programmable conversion start triggers, dual UARTs with LIN support, and three 16-bit reload timers-two with complementary PWM output capability and one with input capture-suitable for motor phase timing and sensor synchronization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LEA | RL78/G13-based; 20 KB Flash, 2.5 KB RAM, lower active current (120 µA/MHz), no on-chip LVD | Preferred for battery-powered devices requiring longer runtime; lacks complementary PWM hardware | Select when energy efficiency outweighs motor control feature set |
| UPD78F0533GK-GAJ-AX | Same 78K0/KB1+ family; 32 KB Flash, 2 KB RAM, additional CAN interface and 12-bit ADC | Suitable for automotive body electronics where CAN bus integration is required | Select when CAN protocol support and higher memory density are mandatory |
Compared with UPD78F0101HMC-5A4-A, R5F100LEA offers superior power efficiency but omits complementary PWM and on-chip LVD, while UPD78F0533GK-GAJ-AX adds CAN and higher-resolution ADC at the cost of larger footprint and higher unit price-making UPD78F0101HMC-5A4-A optimal for cost-sensitive industrial motor and sensor nodes.

FAQ
What is the maximum operating frequency of the UPD78F0101HMC-5A4-A?
The UPD78F0101HMC-5A4-A supports a maximum CPU clock frequency of 16 MHz, achievable using either the internal high-speed oscillator or an external crystal/resonator connected to the X1/X2 pins. At this speed, the minimum instruction execution time is 0.125 µs. The device also supports lower-frequency modes-including sub-MHz STOP and SLOW modes-for power-sensitive applications.
Does the UPD78F0101HMC-5A4-A support in-system programming?
Yes, the UPD78F0101HMC-5A4-A supports full in-system programming (ISP) of its 16 KB on-chip Flash memory via its built-in serial interface using the FLMD0/FLMD1 pins and standard UART commands. This eliminates the need for external programmers during development or field updates, and is documented in the 78K0/KB1+ Flash Memory Self Programming User's Manual (U16701E).
What debug tools are compatible with the UPD78F0101HMC-5A4-A?
The UPD78F0101HMC-5A4-A is fully supported by the QB-78K0MINI On-Chip Debug Emulator, which connects directly to the MCU's dedicated debug interface pins (excluding RESET and VDD/VSS). It enables real-time breakpointing, register inspection, and flash programming without requiring dedicated debug headers or trace pins-reducing board space and BOM cost.
How does the power-on reset (POR) circuit behave in the UPD78F0101HMC-5A4-A?
The UPD78F0101HMC-5A4-A features a fixed 2.1 V ±0.1 V power-on reset threshold, ensuring reliable initialization even during slow-ramp or noisy power-up conditions. This POR circuit is independent of the optional low-voltage detector (LVD) and asserts reset until VDD stabilizes above threshold and internal oscillators settle-guaranteeing deterministic startup without external RC networks.
Can the UPD78F0101HMC-5A4-A operate from a 3.3 V supply?
Yes, the UPD78F0101HMC-5A4-A is fully specified for operation across 2.7 V to 5.5 V, making it compatible with standard 3.3 V systems. All I/O pins are 5 V-tolerant when configured as inputs, and the internal regulator supplies stable core voltage regardless of VDD level-enabling direct interface with both 3.3 V logic and legacy 5 V peripherals without level shifters.
