Product details
Overview
UPD78F1145AGA-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 10-bit ADC (16 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 UPD78F1145AGA-HAB-AX datasheet, UPD78F1145AGA-HAB-AX pinout, UPD78F1145AGA-HAB-AX application, or UPD78F1145AGA-HAB-AX equivalent, key selection considerations include its 100-pin LQFP package, 16-bit CPU core with 16-MHz max operation, Flash endurance (100k write/erase cycles), and support for low-power STOP/IDLE modes in resource-constrained real-time control systems.
Technical Context
The UPD78F1145AGA-HAB-AX implements the 78K0R CPU core with Harvard architecture, supporting 16-bit data paths and 20-bit addressing. It integrates a programmable 16-bit multi-function timer (MTU3) with complementary PWM outputs, a 10-bit successive-approximation ADC with hardware-triggered sampling, and dual serial interfaces (UART + I²C) with independent clock sources.
Its on-chip power management includes three low-power modes (HALT, STOP, IDLE), voltage detection circuitry (VDD monitor with reset generation), and internal voltage regulator (REGC pin) enabling stable 3.3 V or 5 V operation without external LDO. The device uses SuperFlash® technology licensed from SST for Flash memory reliability.

FAQ
What is the maximum operating frequency of the UPD78F1145AGA-HAB-AX?
The UPD78F1145AGA-HAB-AX supports a maximum CPU clock frequency of 20 MHz when using the high-speed on-chip oscillator or an external crystal. This frequency is achievable across the full 2.7–5.5 V supply range and ambient temperature range –40°C to +85°C, as specified in Renesas Electrical Characteristics section of the datasheet.
Does the UPD78F1145AGA-HAB-AX include a hardware debug interface?
Yes, the UPD78F1145AGA-HAB-AX supports on-chip debugging via the single-wire debug (SWD) interface compatible with Renesas E1/E20 emulators. The debug port shares pins with Port 1 (P10–P13), and requires no additional external components beyond standard SWD pull-ups. Full breakpoint and watchpoint functionality is available through RA78K0R IDE integration.
Can the UPD78F1145AGA-HAB-AX operate from a 3.3 V supply without external regulators?
Yes - the UPD78F1145AGA-HAB-AX includes an internal voltage regulator controlled by the REGC pin. When REGC is tied to GND, the device configures for 3.3 V operation; when tied to VDD, it configures for 5.0 V. This eliminates the need for external LDOs in most 3.3 V designs, provided VDD remains within 2.7–5.5 V and meets decoupling requirements.
How many ADC input channels does the UPD78F1145AGA-HAB-AX support?
The UPD78F1145AGA-HAB-AX integrates a 10-bit successive-approximation ADC with 16 analog input channels (AN0–AN15). Channels AN0–AN7 map to Port 2 pins, AN8–AN11 to Port 4, and AN12–AN15 to Port 5. All channels support hardware triggering from timers or external events, and selectable reference sources (VDD or AVREF).
Is the UPD78F1145AGA-HAB-AX pin-compatible with other devices in the 78K0R/KE3 family?
The UPD78F1145AGA-HAB-AX is pin-compatible with the UPD78F1144AGA-HAB-AX and UPD78F1146AGA-HAB-AX in the same 100-pin LQFP package. Differences exist only in Flash size (96 KB / 128 KB / 192 KB) and minor peripheral enablement - all share identical pin functions, electrical characteristics, and register maps, enabling hardware reuse across variants.
