Renesas M30620FCNFP#U3

Overview

M30620FCNFP#U3 from Renesas Electronics is a 16-bit single-chip microcontroller based on the M16C/60 Series CPU core, housed in a 100-pin plastic QFP (100P6S-A). It integrates 128 KB flash memory, 10 KB RAM, 10-bit × 8-channel A/D converter, dual 8-bit D/A converters, five 16-bit output timers and six 16-bit input timers, and supports UART/clock-synchronous serial I/O across five channels - enabling real-time control in office equipment and industrial automation systems.

For engineers reviewing the M30620FCNFP#U3 datasheet, M30620FCNFP#U3 pinout, M30620FCNFP#U3 application, or M30620FCNFP#U3 equivalent, key selection considerations include its 2.4–3.6 V supply range, 62.5 ns minimum instruction cycle at 16 MHz, 87 programmable I/O lines, dual DMAC channels with 25 trigger sources, and built-in CRC-CCITT calculation circuit for data integrity in embedded communications.

Technical Context

The M30620FCNFP#U3 implements a high-efficiency 16-bit CISC architecture with 91 basic instructions and supports three operating modes: single-chip, memory expansion, and microprocessor. Its dual clock generation circuits accept either ceramic resonators (XIN/XOUT) or quartz oscillators (XCIN/XCOUT), enabling flexible timing source selection for system-level synchronization.

Peripheral integration includes a 15-bit watchdog timer with prescaler, programmable I/O ports with software-configurable pull-up resistors (in single-chip mode), and an A/D converter expandable to 18 channels via external multiplexing. The device supports 4 MB memory expansion using four chip-select outputs and 16-/8-bit external bus configurations with address/data multiplexing.

FAQ

What is the maximum operating frequency of the M30620FCNFP#U3?

The M30620FCNFP#U3 achieves a shortest instruction execution time of 62.5 ns at 16 MHz (VCC = 3.0–3.6 V, no software wait states). Its main clock input (XIN) supports up to 16 MHz with ceramic resonators or quartz crystals, and the internal CPU core runs synchronously with this clock - delivering deterministic real-time performance for time-critical control loops.

Does the M30620FCNFP#U3 support in-system programming (ISP)?

Yes, the M30620FCNFP#U3 features 128 KB of on-chip flash memory that supports in-system programming via its on-chip debug interface. This allows firmware updates in the final product without removing the IC, enabling field upgrades, bug fixes, and feature enhancements - a key advantage over mask ROM variants like M30620MCNFP#U3.

How many analog input channels does the M30620FCNFP#U3 A/D converter support?

The M30620FCNFP#U3 integrates a 10-bit successive-approximation A/D converter with 8 dedicated analog input pins (AN00–AN07) on ports P0 and P10–P107. Through software configuration and external multiplexing, the channel count can be expanded to 18 - supporting scalable analog sensing in applications such as multi-zone temperature monitoring or multi-parameter medical devices.

What package type is used for the M30620FCNFP#U3?

The M30620FCNFP#U3 is packaged in a 100-pin plastic molded QFP designated as 100P6S-A - measuring 14 mm × 20 mm with 0.65 mm lead pitch. This RoHS-compliant package supports standard surface-mount assembly processes and provides mechanical stability for industrial environments while enabling dense peripheral routing on PCBs.

Can the M30620FCNFP#U3 operate from a single 3.3 V supply?

Yes, the M30620FCNFP#U3 operates across a supply range of 2.4 V to 3.6 V, making it fully compatible with standard 3.3 V logic systems. At VCC = 3.3 V and f(XIN) = 16 MHz (no wait states), it consumes 66.0 mW - confirming reliable operation under typical 3.3 V rail conditions while maintaining full peripheral functionality including A/D conversion and serial communication.
