Product details
Overview
UPD78F0534AGA-HAB-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KE2 family, featuring 64 KB on-chip flash memory, 4 KB RAM, and a maximum CPU clock of 20 MHz. It integrates 10-bit ADC (8 channels), UART, I²C, and 16-bit timer arrays, and operates across industrial temperature range (−40°C to +85°C) with supply voltage 2.7 V to 5.5 V. It is used in motor control subsystems for HVAC blowers and industrial pump controllers.
For engineers reviewing the UPD78F0534AGA-HAB-AX datasheet, UPD78F0534AGA-HAB-AX pinout, UPD78F0534AGA-HAB-AX application, or UPD78F0534AGA-HAB-AX equivalent, key selection criteria include flash endurance (100,000 erase/write cycles), A/D conversion time (1.2 μs typical), interrupt latency (3–5 cycles), and support for self-programming library Type01 per U17516E.
Technical Context
The UPD78F0534AGA-HAB-AX implements the 78K0S CPU core with 16-bit address space and supports both conventional- and expanded-specification features. Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM), a watchdog timer, and a real-time clock with calendar function.
It uses a single-supply CMOS process with internal voltage regulator (REGC pin), supports in-circuit debugging via QB-MINI2, and executes instructions at 1–2 cycles per instruction depending on addressing mode. Flash memory retention is guaranteed for 20 years at 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | 78K0S 8-bit CISC core with 16-bit address bus and 20 MHz max operation |
| Flash Memory | 64 KB on-chip flash with 100,000 erase/write cycles and 20-year data retention at 85°C |

Pinout & Package
UPD78F0534AGA-HAB-AX is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per Renesas User's Manual Rev.4.01 Section 2.1.4 (78K0/KE2) and validated against pin identification diagrams on pages 51 and 70.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, EVDD | Power supply inputs | VDD powers digital logic; EVDD supplies analog peripherals and ADC reference - separation reduces noise coupling |
| VSS, EVSS | Ground returns | VSS for digital ground; EVSS for analog ground - separate routing required for ADC accuracy |
| AVREF | Analog reference voltage | Accepts external 2.7–5.5 V reference or internal 2.5 V bandgap; sets full-scale range for 10-bit ADC |
| RESET | Active-low reset input | Asynchronous reset assertion halts CPU, clears registers, and forces boot vector fetch from 0000H |
| REGC | Internal regulator control | Connects to 1.0 μF ceramic capacitor to stabilize internal 3.3 V regulator output for core logic |
| P00–P06 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions including UART TX/RX, I²C SCL/SDA, and timer outputs |
| P120–P124 | Port 12 analog inputs | Dedicated ADC input channels (AN0–AN4); support internal sampling capacitor and programmable gain amplifier |
Key Features
| Feature | Design Value |
|---|---|
| Self-programming library support | Enables firmware updates in-system using Type01 library (U18274E), with verified interrupt response time ≤5 cycles |
| Real-time clock with calendar | Hardware RTC runs independently on sub-clock (32.768 kHz), supports alarm, periodic interrupt, and leap-year correction |
| Low-power modes | HALT, STOP, and IDLE modes with wake-up via external interrupt, timer match, or UART activity - current as low as 0.8 μA in STOP |
| On-chip debug interface | Single-wire debug (SWD) compatible with QB-MINI2 emulator; no dedicated debug pins required |
| Flash security lock | Programmable read-out protection bit prevents unauthorized access to flash contents during debugging or mass production |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGAFB#30 | RL78/G13 core; 32 KB flash, 4 KB RAM; lower power (0.52 μA STOP), but no built-in RTC calendar | Lacks hardware calendar and sub-clock domain - requires external RTC or software emulation for date/time | Choose when ultra-low power dominates over calendar functionality and cost sensitivity favors newer RL78 platform |
| UPD78F0533AGA-GAH-AX | Same 78K0/KE2 family; 48 KB flash, identical peripherals and pinout - differs only in flash size and ordering suffix | Direct drop-in replacement where 48 KB program space suffices; same PCB layout and firmware binary compatibility | Select when design does not require full 64 KB flash and BOM cost reduction is prioritized |
Compared with UPD78F0534AGA-HAB-AX, R5F100LGAFB#30 offers superior active power efficiency but sacrifices integrated calendar timekeeping, while UPD78F0533AGA-GAH-AX provides identical peripheral functionality and pin compatibility at reduced memory capacity - enabling direct reuse of hardware and toolchain.

The UPD78F0534AGA-HAB-AX supports a maximum CPU clock frequency of 20 MHz when driven by an external crystal oscillator (X1) or external clock source. This frequency is achievable across the full industrial temperature range (−40°C to +85°C) and supply voltage range (2.7 V to 5.5 V), as confirmed in the AC characteristics section of the 78K0/Kx2 Hardware User's Manual Rev.4.01.
Does the UPD78F0534AGA-HAB-AX include a hardware real-time clock with calendar function?
Yes, the UPD78F0534AGA-HAB-AX integrates a dedicated real-time clock (RTC) module with full calendar support (year/month/day/hour/minute/second), leap-year correction, and alarm interrupt capability. It operates independently on the 32.768 kHz sub-clock and retains timekeeping during STOP mode when backed by VBACK, as documented in Section 1.8 and Chapter 9 of the 78K0/Kx2 User's Manual.
What development tools are officially supported for the UPD78F0534AGA-HAB-AX?
The UPD78F0534AGA-HAB-AX is fully supported by Renesas' QB-MINI2 on-chip debug emulator and the RA78K0 assembler toolchain (Ver.4.01). It also works with CC78K0 C Compiler Ver.4.00 and the PM+ Ver.6.30 IDE. These tools enable full in-circuit debugging, flash programming, and self-programming library integration per U17516E and U18274E application notes.
How many erase/write cycles are guaranteed for the on-chip flash memory in the UPD78F0534AGA-HAB-AX?
The on-chip flash memory in the UPD78F0534AGA-HAB-AX is rated for 100,000 erase/write cycles under standard operating conditions (25°C, VDD = 5.0 V), with data retention guaranteed for 20 years at 85°C. This specification applies to the expanded-specification variant (denoted by "A" in the part number) and is detailed in Section 1.1.4 of the 78K0/Kx2 User's Manual Rev.4.01.
Is the UPD78F0534AGA-HAB-AX pin-compatible with other members of the 78K0/KE2 family?
Yes, the UPD78F0534AGA-HAB-AX shares the same 64-pin LQFP package and pin assignment with other 78K0/KE2 devices including UPD78F0531AGA–UPD78F0537AGA, as defined in Section 2.1.4 of the 78K0/Kx2 User's Manual. This allows hardware reuse across variants differing only in flash size, RAM, or peripheral enablement - such as UPD78F0533AGA-GAH-AX, which is a direct pin-compatible alternative.
