Product details
Overview
UPD78F1143AGK-GAJ-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 of 2.7–5.5 V and targets embedded control in industrial sensors and motor-driven appliances.
For engineers reviewing the UPD78F1143AGK-GAJ-AX datasheet, UPD78F1143AGK-GAJ-AX pinout, UPD78F1143AGK-GAJ-AX application, or UPD78F1143AGK-GAJ-AX equivalent, key selection criteria include its 100-pin LQFP package, Flash endurance (100,000 write/erase cycles), 3.3 V or 5 V operation flexibility, and support for in-circuit debugging via on-chip debug interface.
Technical Context
The UPD78F1143AGK-GAJ-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory structure, 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 system initialization and fault recovery.
Peripheral integration includes three 16-bit timer arrays (each with capture/compare/PWM capability), a 10-bit successive-approximation ADC with internal reference, and dual serial interfaces supporting UART (with LIN support) and I²C bus communication - all mapped to dedicated port pins with configurable pull-up/pull-down and slew-rate control.

The UPD78F1143AGK-GAJ-AX supports a maximum CPU clock frequency of 20 MHz when powered within its specified 2.7–5.5 V supply range. This frequency is achievable using the on-chip PLL or external crystal oscillator input, and the device maintains full peripheral functionality and timing specification compliance at this rate. The UPD78F1143AGK-GAJ-AX datasheet confirms timing parameters such as ADC conversion time and UART baud rate accuracy are guaranteed up to 20 MHz.
Does the UPD78F1143AGK-GAJ-AX support in-system programming (ISP)?
Yes, the UPD78F1143AGK-GAJ-AX supports in-system programming via its on-chip debug interface using the Renesas PG-FP5 programmer or QB-MINI2 emulator. Firmware updates can be performed without removing the device from the target board, leveraging the built-in Flash self-programming capability documented in the 78K0R Self Programming Library Type01 User's Manual (U18706E). This feature is fully implemented in the UPD78F1143AGK-GAJ-AX silicon.
What is the Flash memory endurance rating for the UPD78F1143AGK-GAJ-AX?
The UPD78F1143AGK-GAJ-AX specifies 100,000 write/erase cycles for its 128 KB on-chip Flash memory, with data retention guaranteed for 10 years at 85°C ambient temperature. This endurance rating is validated per Renesas' standard qualification test flow and applies to all sectors of the Flash array. The UPD78F1143AGK-GAJ-AX does not require special wear-leveling firmware for typical embedded control usage patterns.
Can the UPD78F1143AGK-GAJ-AX operate from a 3.3 V supply only?
Yes, the UPD78F1143AGK-GAJ-AX operates reliably across 2.7–5.5 V, making it fully compatible with 3.3 V systems. All I/O pins are 5 V tolerant when configured as inputs, and the internal voltage regulator supports stable core operation at 3.3 V. The UPD78F1143AGK-GAJ-AX electrical specifications confirm that AC/DC parameters - including propagation delay, setup/hold times, and ADC accuracy - are guaranteed across the entire voltage range, including 3.3 V nominal operation.
Is there hardware support for CRC calculation in the UPD78F1143AGK-GAJ-AX?
Yes, the UPD78F1143AGK-GAJ-AX includes a dedicated 16-bit hardware CRC generator accessible via SFR registers. It supports both CRC-16-CCITT and custom polynomial configurations, and can process data blocks directly from RAM or peripheral FIFOs without CPU intervention. This accelerator is explicitly documented in the UPD78F1143AGK-GAJ-AX User's Manual (U17854EJ9V0UD) Chapter 12 and is active in all power modes except HALT.
