For engineers reviewing the UPD78F1500AGK-GAK-M1-AX datasheet, UPD78F1500AGK-GAK-M1-AX pinout, UPD78F1500AGK-GAK-M1-AX application, or UPD78F1500AGK-GAK-M1-AX equivalent, key selection considerations include its 100-pin LQFP package, on-chip voltage regulator (REGC pin), segment LCD driver support (up to 8×32 segments), and compliance with industrial-grade temperature range (−40°C to +85°C).

Technical Context

The UPD78F1500AGK-GAK-M1-AX implements the 78K0R CPU core with 16-bit architecture, supporting both 8-bit and 16-bit instructions. It features dual-voltage operation: 3.0–5.5 V for I/O and internal logic, and dedicated analog supply pins (AVDD0/AVSS) for the 10-bit ADC to ensure noise immunity.

Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM capability), a watchdog timer with independent clock source, and hardware multiplier/divider. The device supports in-circuit debugging via QB-MINI2 and flash programming via PG-FP5, with on-chip boot ROM enabling serial programming without external programmer.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the UPD78F1500AGK-GAK-M1-AX?

The UPD78F1500AGK-GAK-M1-AX operates at a maximum frequency of 20 MHz using its on-chip high-speed system clock. This frequency is achievable across the full industrial temperature range (−40°C to +85°C) when supplied with 3.0–5.5 V. The device supports multiple clock sources including external crystal (up to 20 MHz), ceramic resonator, or internal high-speed oscillator (8 MHz, ±2% accuracy). Frequency scaling is managed via the system clock control register (CKC).

Does the UPD78F1500AGK-GAK-M1-AX include an integrated LCD driver?

Yes, the UPD78F1500AGK-GAK-M1-AX includes a dedicated segment-type LCD controller supporting up to 8 commons and 32 segments (256 total segments). It provides internal bias voltage generation, programmable duty cycle (1/2 to 1/8), and frame frequency control. The SEGxx and COM0–COM7 pins are physically mapped to specific port pins in the 100-pin LQFP package and require no external bias resistors or frame controllers.

What is the role of the REGC pin on the UPD78F1500AGK-GAK-M1-AX?

REGC is the control terminal for the on-chip voltage regulator that generates a stable 3.3 V supply for internal logic circuits. When enabled, it reduces dependency on external regulators and simplifies power design. A 1 μF ceramic capacitor must be connected between REGC and VSS. The regulator output is internally routed - no external connection is required. Its activation is controlled via the REGCR register in the special function register (SFR) space.

How much Flash and RAM does the UPD78F1500AGK-GAK-M1-AX contain?

The UPD78F1500AGK-GAK-M1-AX contains 128 KB of on-chip Flash memory for program storage and 8 KB of RAM for data and stack operations. Additionally, it includes 1 KB of data flash memory - a separate EEPROM-like area with 100,000 write/erase cycles - used for storing calibration parameters, device identifiers, or field-updatable configuration data without affecting main program Flash.

Which development tools support the UPD78F1500AGK-GAK-M1-AX?

The UPD78F1500AGK-GAK-M1-AX is supported by Renesas' full toolchain: the CC78K0R C compiler, RA78K0R assembler, QB-MINI2 on-chip debugger (with flash programming), and PG-FP5 external flash programmer. Evaluation is enabled via the QB-78K0RLX3 in-circuit emulator. All tools interface through the standard 14-pin JTAG connector defined in the 78K0R/LF3 hardware manual.
