It features 96 KB + 4 KB Flash program memory, 5 KB RAM, 10-bit A/D converter with 18 channels, dual 16-bit multifunction timers (Timer A/B), and three serial interfaces supporting UART, clock-synchronous, I²C Bus, and IEBus. It operates at up to 16 MHz (62.5 ns min instruction time) across 2.7–5.5 V supply and targets embedded control in office equipment and industrial systems.

For engineers reviewing the M30302FAPFP#U5 datasheet, M30302FAPFP#U5 pinout, M30302FAPFP#U5 application, or M30302FAPFP#U5 equivalent, key selection criteria include its 100-pin QFP package, Flash reprogrammability (100 erase/write cycles), -20°C to +85°C operating range, integrated DMAC and CRC circuit, and support for single-chip, memory expansion, and microprocessor modes.

Technical Context

The M30302FAPFP#U5 implements the M16C/60 Series CPU core with 91 basic instructions and supports three operation modes: single-chip, memory expansion, and microprocessor. Its memory architecture provides 1 Mbyte address space, with on-chip Flash organized as 96 KB main + 4 KB Block A for flexible firmware partitioning.

Peripheral integration includes two independent 16-bit timer groups (Timer A ×3, Timer B ×3), three serial interface channels (UART/clock-sync/I²C/IEBus), and a 10-bit A/D converter with 18 analog inputs including extended pins ANEX0/ANEX1. The device uses dual clock sources - main (XIN/XOUT, up to 16 MHz) and sub (XCIN/XCOUT, 32 kHz) - with internal feedback resistors eliminating external components.

FAQ

What is the Flash memory organization and endurance rating of the M30302FAPFP#U5?

The M30302FAPFP#U5 contains 96 KB + 4 KB Flash memory, with the 4 KB Block A enabling safe firmware updates. It supports 100 program/erase cycles across the entire Flash array. This endurance is specified under standard conditions (3.3±0.3 V or 5.0±0.5 V programming voltage) and is validated for industrial temperature operation (-20°C to +85°C). The M30302FAPFP#U5 does not support sector-erase granularity beyond the full-array specification.

Does the M30302FAPFP#U5 support IEBus communication natively, and what pins are used?

Yes, the M30302FAPFP#U5 integrates full IEBus (Inter Equipment Bus) protocol support in hardware, compliant with NEC's IEBus standard. It uses dedicated pins P6_6 (SCL1), P6_7 (SDA1), and P6_4 (CLKS1) for IEBus clock, data, and transfer clock output. No external transceiver is required, and the M30302FAPFP#U5 handles arbitration, collision detection, and frame formatting in silicon.

What are the power supply requirements and low-power modes supported by the M30302FAPFP#U5?

The M30302FAPFP#U5 requires dual supply rails: VCC1 = VCC2 = 2.7–5.5 V, with strict voltage matching. It supports wait mode (1.8 μA at 3 V/32 kHz) and stop mode (0.7 μA at 3 V), both retaining RAM content and register state. The device exits stop mode via RESET, NMI, or selected INT pins. The M30302FAPFP#U5 does not support deep-sleep or real-time clock (RTC) autonomous wake-up without external circuitry.

How many analog input channels does the M30302FAPFP#U5 A/D converter support, and what is its resolution?

The M30302FAPFP#U5 integrates a single 10-bit successive-approximation A/D converter with 18 total analog input channels: eight standard (AN0–AN7), eight auxiliary (AN0_0–AN0_7), and two extended (ANEX0, ANEX1). ANEX0 functions as bidirectional (input/output) in external op-amp configurations. All channels share the same 10-bit resolution and reference voltage (VREF), with conversion time dependent on clock source and resolution setting.

What is the package type and pin count of the M30302FAPFP#U5, and is it RoHS-compliant?

The M30302FAPFP#U5 is packaged in a 100-pin plastic QFP (PRQP0100JB-A, also known as 100P6S-A) with 0.65 mm lead pitch. It is lead-free and RoHS-compliant, meeting EU Directive 2011/65/EU. The #U5 suffix denotes the -20°C to +85°C operating temperature grade and lead-free finish. This package is surface-mount compatible and requires standard reflow profiles for lead-free soldering.
