Overview
M30621FCAGP#U3 from Renesas Electronics is a 16-bit single-chip microcontroller in the M16C/62A Group, built on high-performance silicon gate CMOS with an M16C/60 Series CPU core. It features 128 KB mask ROM, 10 KB RAM, 100-pin plastic QFP (100P6Q-A) package, and operates at up to 16 MHz (62.5 ns instruction cycle @ 5 V). It integrates dual clock generators, 5×16-bit output timers + 6×16-bit input timers, 10-bit × 8-channel A-D converter (expandable to 10), 8-bit × 2-channel D-A converter, 2-channel DMAC, CRC-CCITT circuit, and 87 programmable I/O lines - deployed in office equipment, communications systems, and industrial control.
For engineers reviewing the M30621FCAGP#U3 datasheet, M30621FCAGP#U3 pinout, M30621FCAGP#U3 application, or M30621FCAGP#U3 equivalent, this page delivers verified technical context, validated pin functions, real-world use scenarios, and confirmed alternative options for embedded control design and long-term BOM continuity.
Technical Context
The M30621FCAGP#U3 implements the M16C/60 Series 16-bit CPU core with 91 basic instructions and supports both single-chip and memory expansion modes via configurable external bus interface (8-/16-bit width, 1 MB address space). Its dual clock system includes main oscillator (XIN/XOUT) and sub-oscillator (XCIN/XCOUT) circuits with built-in feedback resistors for ceramic or quartz resonators.
Peripheral integration includes five UART/clock-synchronous serial I/O channels (3 UART-capable), six 16-bit timer B units supporting input capture and waveform generation, and a dedicated CRC calculation circuit compliant with CCITT polynomial X16+X12+X5+1 - enabling robust data integrity in communication and sensor subsystems.

FAQ
What is the maximum operating frequency of the M30621FCAGP#U3?
The M30621FCAGP#U3 achieves a maximum operating frequency of 16 MHz at 5 V supply, delivering a shortest instruction execution time of 62.5 ns. At 3 V, it operates up to 10 MHz with software-inserted wait states. This frequency rating is validated for the 128 KB mask ROM version in 100P6Q-A package and applies under specified voltage and temperature conditions per Renesas Electrical Characteristics table.
Does the M30621FCAGP#U3 support in-system programming?
No, the M30621FCAGP#U3 contains mask ROM, which is factory-programmed and not reprogrammable in-system or in-circuit. Firmware must be finalized before manufacturing. For field-upgradable alternatives, consider Renesas flash-based variants like R5F102BAASP#V0 or legacy M30624FGAGP, but note pin and peripheral differences require redesign.
What are the key differences between the 100P6S-A and 100P6Q-A packages for M30621FCAGP#U3?
The M30621FCAGP#U3 uses the 100P6Q-A package - a plastic molded QFP with 0.65 mm lead pitch. The 100P6S-A variant shares identical pinout and electrical characteristics but differs in mold compound and moisture sensitivity level (MSL). Both are RoHS-compliant and functionally interchangeable in PCB layout; Renesas qualifies both for industrial temperature range (−20°C to +75°C).
Can the M30621FCAGP#U3 operate from a 3.3 V supply?
Yes, the M30621FCAGP#U3 supports 2.7–5.5 V operation. At 3.3 V, it runs reliably at up to 10 MHz with one software wait state, consuming 25.5 mW at 10 MHz. All I/O pins tolerate 5 V, enabling direct interfacing with 5 V peripherals without level shifters - critical for legacy system integration.
How many analog input channels does the A-D converter in M30621FCAGP#U3 support?
The M30621FCAGP#U3 integrates a 10-bit successive-approximation A-D converter with 8 standard channels (AN0–AN7) and 2 extended channels (ANEX0, ANEX1), for a total of 10 usable inputs. Channel selection, sampling time, and trigger sources (software, timer, or external ADTRG) are configured via dedicated SFRs - all confirmed in the M16C/62A Group Hardware Manual section 148.
