Integrated multi-channel ADC for analog signal sensing

Watchdog timer for fail-safe operation

Low-power modes for battery and energy-saving designs

Internal and external clock options for flexible timing

Wide operating temperature range suitable for industrial environments

RoHS-compliant, lead-free manufacturing

Key Advantages

Mature, proven platform with broad industry adoption

Stable performance and robust peripheral set for many control tasks

Low power consumption helps reduce system energy use

Flash memory simplifies updates and field maintenance

Scalable family makes design reuse easier across models

Strong reliability for long product life cycles

Broad ecosystem and documentation simplify development and support

Packaging

Package family code: GK(A)-GAK-AX; supplier case code: 627

RoHS-compliant, lead-free molded plastic IC package

Surface-mount leaded package type used widely in embedded systems (dimensions, pin count, and lead pitch are defined by NEC for this package code)

Pin configuration follows the uPD78F0547 series pinout (check the datasheet for exact pin map and functions)

Moisture Sensitivity Level, recommended reflow profile, and handling guidelines are specified in the datasheet

Thermal characteristics (e.g., θJA/θJC) are provided by the manufacturer for accurate thermal design

Electrical properties (ESD ratings, I/O drive capability, input thresholds, 5 V tolerance for certain pins if applicable, and operating voltage range) are documented in the datasheet

For exact package size, footprint, and mechanical drawings, refer to the package section of the datasheet on our website

Lifecycle

Status: Mature product from NEC’s 78K line; availability can vary by region and date code. Some 78K family parts have transitioned or been superseded in many applications.

Recommended alternatives and successors:

- Renesas RL78/G13 family (modern successor to 78K, lower power, richer peripherals)

- Renesas RL78/G14 family (more performance and peripherals for advanced control)

- NEC/Renesas uPD78F0545 and uPD78F0546 (same family; potential board-level or pin-compatible alternatives depending on your design)

Important: Compatibility (pinout, timing, voltage, software) must be verified against your design requirements and the datasheets.

If an exact equivalent cannot be confirmed, please contact our sales team via our website for up-to-date lifecycle and cross-reference support.
