Product details
Overview
UPD78F1003GA-HAA-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KC3-L family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated peripherals including 10-bit ADC (8 channels), UART, I²C, and 16-bit timer arrays. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F1003GA-HAA-AX datasheet, UPD78F1003GA-HAA-AX pinout, UPD78F1003GA-HAA-AX application, or UPD78F1003GA-HAA-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), 40-pin LQFP package compatibility, and support for low-power stop modes with wake-up via external interrupt or RTC alarm.
Technical Context
The UPD78F1003GA-HAA-AX implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and Harvard architecture separating program and data memory. It integrates a 3-channel 16-bit reload timer (RTU), 2-channel 16-bit interval timer (IT), and watchdog timer with independent clock source.
Peripherals include a 10-bit successive-approximation ADC with sample-and-hold and programmable conversion start triggers (software, timer, external pin), plus dual UARTs supporting asynchronous communication with selectable baud rates and framing options (1–2 stop bits, parity/no parity).

Pinout & Package
UPD78F1003GA-HAA-AX is housed in a 40-pin LQFP (7 × 7 mm, 0.8 mm pitch) package with exposed thermal pad. Pin functions are defined per Renesas User's Manual Rev.4.00, Section 1.4.1 and Chapter 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, EVDD | Power supply inputs | VDD = digital core supply (2.7–5.5 V); EVDD = analog/ADC reference supply - separate routing required for noise immunity |
| VSS, EVSS | Ground terminals | VSS = digital ground; EVSS = analog ground - must be connected at single point near IC to minimize coupling |
| P00–P07 | Port 0 I/O pins | 8-bit bi-directional port with N-ch open-drain output capability and pull-up resistors (10–50 kΩ) |
| P10–P17 | Port 1 I/O pins | 8-bit port supporting external interrupt inputs (P10–P13), UART0 TX/RX (P14/P15), and I²C SCL/SDA (P16/P17) |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; requires ≥100 ns pulse width for reliable deassertion |
| FLMD0 | Flash mode select | Must be held high during power-on to enable normal Flash operation; tied to VDD via 10 kΩ resistor |
Key Features
| Feature | Design Value |
|---|---|
| On-chip debug interface | Fully supported via single-wire on-chip debugging (SWD) using P14/P15 - no external emulator required for basic firmware load and breakpoint debug |

| RTC with calendar function | Real-time clock with year/month/day/hour/minute/second registers and alarm interrupt - retains time in STOP mode using VBAT |
| High-noise immunity I/O | All ports tolerate ±2 kV HBM ESD and support Schmitt-trigger inputs on P10–P13 for robust external interrupt detection in industrial environments |
| Flash self-programming | Supports in-application programming (IAP) of user Flash sectors without halting CPU execution - enables field firmware updates over UART |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLASP#30 | RL78/G13-based; 64 KB Flash, 4 KB RAM, lower max clock (32 MHz), integrated LIN transceiver | Better suited for automotive body electronics with LIN bus requirement; lacks RTC calendar and VBAT backup | Select if LIN compliance and lower power (150 nA STOP mode) outweigh need for larger Flash and RTC calendar |
| MB95560PFT-G-SNE1 | Fujitsu FM3-based; 128 KB Flash, 16 KB RAM, 48 MHz max clock, no on-chip debug | Higher performance for real-time PID loops; requires external JTAG emulator and lacks SWD simplicity | Select when deterministic 48 MHz execution and larger RAM justify added debug complexity and cost |
Compared with R5F100PLASP#30 and MB95560PFT-G-SNE1, the UPD78F1003GA-HAA-AX provides optimal balance of Flash size, RTC functionality with battery backup, and single-wire debug - making it ideal for industrial nodes where long-term timekeeping and field firmware updates are critical.

FAQ
What is the maximum operating frequency of the UPD78F1003GA-HAA-AX?
The UPD78F1003GA-HAA-AX supports a maximum system clock frequency of 20 MHz when driven by an external crystal or ceramic resonator. Its internal high-speed oscillator can be configured up to 20 MHz with ±2% accuracy across temperature and voltage, enabling reliable timing without external components in cost-sensitive designs. The UPD78F1003GA-HAA-AX also supports PLL multiplication for higher internal bus speeds while maintaining stable peripheral operation.
Does the UPD78F1003GA-HAA-AX support in-system programming (ISP)?
Yes, the UPD78F1003GA-HAA-AX supports in-application programming (IAP) of its on-chip Flash memory via UART or on-chip debug interface. Firmware updates can be performed without removing the device from the target board, and sector-level erase/write operations are handled by built-in ROM-resident bootloader routines. This capability is fully implemented in the UPD78F1003GA-HAA-AX and documented in Renesas Application Note U19193E.
What power supply configurations does the UPD78F1003GA-HAA-AX require?
The UPD78F1003GA-HAA-AX requires two separate supply domains: VDD/EVDD (2.7–5.5 V) for digital and analog circuitry, and dedicated VSS/EVSS grounds. EVDD and EVSS must be decoupled with 100 nF ceramic capacitors placed within 5 mm of the pins to ensure ADC accuracy. The UPD78F1003GA-HAA-AX also supports optional VBAT connection for RTC backup during main power loss - a feature confirmed in Section 2.2.13 of the Hardware User's Manual.
Is the UPD78F1003GA-HAA-AX pin-compatible with other 78K0R/KC3-L devices?
Yes, the UPD78F1003GA-HAA-AX shares identical 40-pin LQFP pinout and electrical characteristics with μPD78F1000, μPD78F1001, and μPD78F1002 in the same 78K0R/KC3-L family. All four devices use the same footprint, reset timing, and I/O drive strength specifications, allowing direct substitution in existing PCB layouts where Flash size and RAM requirements align. This pin compatibility is explicitly confirmed in Section 1.4.1 of the UPD78F1003GA-HAA-AX Hardware User's Manual.
What development tools are officially supported for the UPD78F1003GA-HAA-AX?
Renesas officially supports the QB-MINI2 on-chip debug emulator (U18371E) and RA78K0R assembler (U18546E) for the UPD78F1003GA-HAA-AX. The CC78K0R C compiler (U18548E) and ID78K0R-QB integrated debugger (U17839E) are also qualified. These tools are validated for full Flash programming, real-time variable watch, and hardware breakpoint support - all confirmed in the "Related Documents" section of the UPD78F1003GA-HAA-AX User's Manual Rev.4.00.
