Product details
Overview
UPD78F1144AGA-HAB-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KE3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated peripherals including 12-bit ADC, UART, I²C, and timer modules. It operates at up to 20 MHz with supply voltage range of 2.7 V to 5.5 V and targets embedded control in industrial sensors, motor drives, and appliance HMI systems.
For engineers reviewing the UPD78F1144AGA-HAB-AX datasheet, UPD78F1144AGA-HAB-AX pinout, UPD78F1144AGA-HAB-AX application, or UPD78F1144AGA-HAB-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), operating temperature range (−40°C to +85°C), and support for on-chip debug via single-wire interface - all critical for cost-sensitive, long-lifecycle industrial firmware deployments.
Technical Context
The UPD78F1144AGA-HAB-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a programmable low-voltage detector (LVD), watchdog timer (WDT), and power-on reset (POR) circuitry for robust operation in noisy environments.
Peripheral integration includes a 12-channel 12-bit ADC with sample-and-hold, three 16-bit timer arrays (each supporting PWM, input capture, and output compare), and dual serial interfaces (UART and I²C) with independent clock sources - enabling concurrent communication and real-time signal processing without external co-processors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 78K0R 16-bit CPU with 20 MHz max clock; enables deterministic real-time control loops with sub-μs interrupt latency. |
| Flash Memory | 128 KB on-chip Flash with 100,000 write/erase cycles; supports in-system programming (ISP) and secure boot verification. |
| RAM Size | 8 KB on-chip RAM; sufficient for stack, heap, and real-time data buffers in sensor fusion or motor commutation algorithms. |
| ADC Resolution | 12-bit successive approximation ADC with 12 input channels; delivers ±1 LSB INL for precision analog sensing in industrial transducers. |
| Supply Voltage | 2.7 V to 5.5 V operation; allows direct interfacing with legacy 5 V logic and compatibility with modern 3.3 V subsystems. |
| Operating Temp | −40°C to +85°C industrial grade; validated for use in enclosed motor drives and HVAC control panels without derating. |
| I/O Pins | 80-pin LQFP package with 64 CMOS I/Os; supports configurable pull-up/down, open-drain, and high-current drive (20 mA sink/source). |
Pinout & Package
UPD78F1144AGA-HAB-AX is housed in an 80-pin LQFP (12 mm × 12 mm, 0.5 mm pitch) package with exposed thermal pad. Pin assignments follow Renesas' standardized 78K0R/KE3 layout, supporting full peripheral mapping and debug access.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / EVDD | Power supply inputs | Dual VDD (core) and EVDD (I/O) rails enable independent noise filtering and voltage scaling for mixed-signal stability. |
| VSS / EVSS | Ground returns | Separate analog (AVSS) and digital (VSS/EVSS) grounds reduce coupling between ADC and switching peripherals. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; accepts external debounced signal or RC network for system-level fault recovery. |
| FLMD0 | Flash mode select | Configures boot source at power-on: internal Flash (normal operation) or ROM-based bootloader (programming mode). |
| P00–P06 | Port 0 bidirectional I/O | Supports UART0 TX/RX, timer outputs, and general-purpose functions; each pin configurable for alternate functions via SFRs. |
| AVREF | Analog reference input | Accepts external 2.5 V to 5.5 V reference or connects to internal VDD; sets full-scale range for 12-bit ADC conversions. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip Flash with EEPROM emulation | Uses dedicated Flash sectors to emulate EEPROM functionality (1 KB user area), enabling nonvolatile parameter storage without external components. |
| Single-wire on-chip debug interface | Requires only one I/O pin (P130) for full debug visibility - no JTAG header needed, reducing PCB footprint and BOM cost. |
| Programmable low-voltage detector | LVD threshold selectable from 1.6 V to 4.2 V in 0.2 V steps; triggers interrupt or reset to prevent erratic operation during brown-out conditions. |
| 16-bit timer array with PWM output | Three independent timer units support complementary PWM generation with dead-time insertion - suitable for 3-phase inverter gate driving. |
| Hardware I²C master/slave mode | Full I²C compliance (100 kHz/400 kHz), automatic ACK/NACK handling, and arbitration recovery - simplifies communication with sensors and PMICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFB#30 | RL78/G13-based; 32 KB Flash, 4 KB RAM, lower power (125 μA/MHz), but no hardware I²C. | Better suited for ultra-low-power battery nodes where I²C is handled by software bit-banging or external bridge. | Select when energy efficiency outweighs peripheral richness and Flash size is sufficient for simplified firmware. |
| MB95560PMT-G-SNE1 | Fujitsu FM3-based; 256 KB Flash, 32 KB RAM, Cortex-M0+ core, but requires external crystal and lacks single-wire debug. | Targets higher-complexity applications needing larger code space and ARM ecosystem tooling, at cost of increased BOM and layout complexity. | Select when migrating to ARM toolchains is prioritized and debug infrastructure already supports SWD/JTAG. |
Compared with UPD78F1144AGA-HAB-AX, R5F100PLAFB#30 trades Flash capacity and hardware I²C for lower active current, while MB95560PMT-G-SNE1 offers ARM compatibility and larger memory at the expense of debug simplicity and external timing component requirements.
