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-driven appliances.
For engineers reviewing the UPD78F1142AGK-GAJ-AX datasheet, UPD78F1142AGK-GAJ-AX pinout, UPD78F1142AGK-GAJ-AX application, or UPD78F1142AGK-GAJ-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), operating temperature range (−40°C to +85°C), and QFP-64 package compatibility with legacy 78K0R designs.
Technical Context
The UPD78F1142AGK-GAJ-AX implements the 78K0R CPU core with 16-bit architecture, supporting both standard and expanded-specification instruction sets. It integrates a programmable low-voltage detector (LVD) with 3 selectable thresholds (2.7 V, 3.3 V, 4.2 V) and a watchdog timer with independent clock source (10 kHz on-chip oscillator).
Its peripheral set includes a 16-bit multifunction timer array unit (TAU) with capture/compare/PWM functions, a serial interface controller (SIC) configurable as UART or I²C, and an on-chip debug interface compatible with QB-MINI2 emulator. All peripherals are memory-mapped and controlled via dedicated SFRs.

FAQ
What is the maximum operating frequency of the UPD78F1142AGK-GAJ-AX?
The UPD78F1142AGK-GAJ-AX supports a maximum CPU clock frequency of 20 MHz when powered within its specified supply voltage range (2.7 V to 5.5 V). This frequency is achieved using the on-chip high-speed oscillator or an external crystal up to 20 MHz. At 20 MHz, the UPD78F1142AGK-GAJ-AX delivers approximately 12.5 MIPS performance, sufficient for real-time motor control and multi-sensor data acquisition tasks.
Does the UPD78F1142AGK-GAJ-AX support in-system programming (ISP)?
Yes, the UPD78F1142AGK-GAJ-AX supports in-system programming via its on-chip serial interface using the Renesas Flash Development Toolkit (FDT) and compatible debug adapters like QB-MINI2. The UPD78F1142AGK-GAJ-AX includes a ROM-resident bootloader that enables Flash reprogramming without removing the device from the target board, supporting field firmware updates and production-line programming.
What is the ADC resolution and channel count of the UPD78F1142AGK-GAJ-AX?
The UPD78F1142AGK-GAJ-AX integrates a 10-bit successive approximation ADC with 16 input channels. It achieves ±1 LSB integral nonlinearity (INL) and differential nonlinearity (DNL) across the full operating temperature range. Conversion time is 1.2 μs per channel, and the ADC supports hardware-triggered scan mode for synchronized sampling across multiple channels - a key capability used in the UPD78F1142AGK-GAJ-AX for energy metering and sensor fusion applications.
Is the UPD78F1142AGK-GAJ-AX pin-compatible with other devices in the 78K0R/KE3 family?
The UPD78F1142AGK-GAJ-AX shares the same 64-pin LQFP package and pin assignment with other members of the 78K0R/KE3 expanded-specification series (e.g., UPD78F1143AGK-GAJ-AX, UPD78F1144AGK-GAJ-AX), enabling hardware reuse across variants. However, it is not pin-compatible with conventional-specification devices (e.g., μPD78F1142) due to differences in peripheral mapping and SFR layout - always verify pin function tables in the UPD78F1142AGK-GAJ-AX User's Manual before migration.
What debug tools are officially supported for the UPD78F1142AGK-GAJ-AX?
Renesas officially supports the QB-MINI2 On-Chip Debug Emulator with Programming Function for the UPD78F1142AGK-GAJ-AX. This tool provides full real-time debugging, flash programming, and trace capabilities via the on-chip debug interface. Additional compatible tools include the ID78K0R-QB integrated debugger and RA78K0R assembler package. The UPD78F1142AGK-GAJ-AX does not support JTAG; debugging relies exclusively on Renesas' proprietary 2-wire SWD-like interface.
