For engineers reviewing the UPD78F1152AGC-GAD-AX datasheet, UPD78F1152AGC-GAD-AX pinout, UPD78F1152AGC-GAD-AX application, or UPD78F1152AGC-GAD-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +85°C), and compatibility with RA78K0R C compiler and QB-MINI2 on-chip debugger.

Technical Context

The UPD78F1152AGC-GAD-AX implements the 78K0R CPU core with Harvard architecture, supporting 16-bit data paths and 24-bit addressing. It integrates a 12-bit successive-approximation ADC with 16 input channels and programmable sampling time, plus three 16-bit timer arrays (TAU) with PWM output capability and capture/compare functions.

Its peripheral set includes two full-duplex UARTs with LIN support, one I²C interface compliant with SMBus v2.0, and a watchdog timer with independent clock source. The device uses SuperFlash® technology for nonvolatile memory, enabling single-cycle erase and byte-wise programming.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the UPD78F1152AGC-GAD-AX?

The UPD78F1152AGC-GAD-AX operates at a maximum system clock frequency of 20 MHz. This frequency is supported across its full specified voltage range (2.7 V to 5.5 V) and temperature range (−40°C to +85°C). At 20 MHz, the device achieves approximately 13.3 million instructions per second (MIPS), enabling deterministic execution of real-time control algorithms such as motor commutation or sensor fusion. The UPD78F1152AGC-GAD-AX uses an on-chip PLL to generate internal clocks from external crystal or ceramic resonator sources.

Does the UPD78F1152AGC-GAD-AX support in-system programming (ISP)?

Yes, the UPD78F1152AGC-GAD-AX supports in-system programming via its on-chip debug interface using the RESET pin as a single-wire debug channel. It also enables in-application programming (IAP) through the built-in Flash memory controller, allowing firmware updates without halting system operation. The UPD78F1152AGC-GAD-AX requires no external high-voltage programming signals - all programming voltages are generated internally. Renesas provides PG-FP4 and PG-FP5 programmers for production programming, and the UPD78F1152AGC-GAD-AX is fully compatible with RA78K0R development tools.

What is the Flash memory endurance specification for the UPD78F1152AGC-GAD-AX?

The UPD78F1152AGC-GAD-AX features 128 KB of on-chip SuperFlash® memory rated for 100,000 write/erase cycles per block and guaranteed data retention of 20 years at +85°C. This endurance applies to both bulk erase and sector erase operations, and the memory supports byte-wise programming. The UPD78F1152AGC-GAD-AX includes hardware error detection during programming and erase, and its Flash controller prevents partial writes during power loss via automatic suspend/resume functionality.

How many ADC input channels does the UPD78F1152AGC-GAD-AX support?

The UPD78F1152AGC-GAD-AX integrates a 12-bit successive-approximation ADC with 16 selectable input channels (AN0–AN15), mapped across multiple I/O ports including P10–P17 and P40–P43. It supports programmable sampling time, hardware-triggered conversions via timer or external event, and result storage in dual-buffered registers. The UPD78F1152AGC-GAD-AX ADC achieves ±1 LSB integral nonlinearity (INL) and supports differential input mode on selected channel pairs for noise rejection in industrial signal conditioning.

Is the UPD78F1152AGC-GAD-AX pin-compatible with other devices in the 78K0R/KE3 family?

The UPD78F1152AGC-GAD-AX shares the same 100-pin LQFP package and pinout as other 78K0R/KE3 devices in the μPD78F114x and μPD78F115x series, including μPD78F1146A(A) and μPD78F1156AGC-GAD-AX. Pin compatibility extends to power, ground, reset, clock, and primary peripheral signals (UART, I²C, ADC inputs, timer outputs). However, certain port pins may differ in alternate function mapping - always verify against the specific device's pin function table before board reuse. The UPD78F1152AGC-GAD-AX is not pin-compatible with earlier 78K0 or 78K/III devices due to architectural and peripheral differences.
