Product details
Overview
M30621FCMGP#U3 from Renesas Electronics is a 16-bit single-chip microcontroller based on the M16C/60 Series CPU core, featuring 256 KB flash memory, 20 KB RAM, 10-bit 8-channel ADC with 2-channel expansion, dual 8-bit DACs, and two 2-channel DMACs. It operates at up to 16 MHz (62.5 ns instruction cycle) with 4.2–5.5 V supply and supports office equipment, industrial control, and communications systems.
For engineers reviewing the M30621FCMGP#U3 datasheet, M30621FCMGP#U3 pinout, M30621FCMGP#U3 application, or M30621FCMGP#U3 equivalent, key selection criteria include its 100-pin QFP package, integrated UART/clock-synchronous serial I/O (5 channels), 11 timer units (5 TA + 6 TB), CRC-CCITT calculation circuit, and watchdog timer - all critical for real-time embedded control in resource-constrained designs.
Technical Context
The M30621FCMGP#U3 implements the M16C/60 CPU core with 91 basic instructions and a 1 MB address space. Its dual clock generation circuits support main (XIN/XOUT) and sub (XCIN/XCOUT) oscillators using quartz or ceramic resonators, enabling precise timing for mixed-signal applications.
It integrates five 16-bit output timers (TA0–TA4) and six 16-bit input timers (TB0–TB5), plus UART0–UART2 and SI/O3–SI/O4 for flexible serial communication. The A-D converter includes programmable trigger sources (ADTRG), and the D-A converter outputs are multiplexed with TB3IN/TB4IN pins.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFB#30 | RL78/G13 core, 128 KB flash, 12 KB RAM, lower max frequency (24 MHz), integrated LIN transceiver | Better suited for automotive body electronics with LIN bus; lacks dual DAC and sub-oscillator (XCIN/XCOUT) | Select when LIN compliance and lower power (170 µA/MHz) outweigh need for DACs and dual clock domains |
| MB9BF506RPMC-G-S2 | ARM Cortex-M3 core, 512 KB flash, 64 KB RAM, 32-bit architecture, no on-chip DAC | Higher throughput for complex algorithms; requires external DAC for analog output; larger footprint (144-pin LQFP) | Select when migrating to 32-bit ecosystem and prioritizing code density, interrupt latency, and toolchain continuity over analog integration |

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the M30621FCMGP#U3?
The M30621FCMGP#U3 achieves a maximum operating frequency of 16 MHz with a shortest instruction execution time of 62.5 ns under 5 V supply conditions. At 10 MHz and 3 V (with software one-wait), the instruction cycle extends to 100 ns. These values are confirmed in the M16C/62A Group datasheet Section 1.1.1 and apply specifically to the flash memory 5V version represented by M30621FCMGP#U3.
Does the M30621FCMGP#U3 support external memory expansion, and what address space is available?
Yes, the M30621FCMGP#U3 supports external memory expansion up to 1 MB (00000h–FFFFFh), using A0–A19 address lines, CS0–CS3 chip selects, and RD/WR control signals. The internal memory map reserves FFFFFh downward for ROM and 00400h upward for RAM, with SFRs occupying 00000h–003FFh - all documented in the M16C/62A Group Memory section (Page 10).
How many analog-to-digital converter channels does the M30621FCMGP#U3 provide, and what is their resolution?
The M30621FCMGP#U3 integrates a 10-bit A-D converter with eight primary input channels (AN0–AN7 on P100–P107) and two expandable channels (ANEX0/ANEX1 on P95/P96), for a total of ten usable channels. Resolution is fixed at 10 bits, with conversion triggered by software, timer, or external ADTRG signal - as specified in Section 148 of the M16C/62A Group documentation.
Can the M30621FCMGP#U3 generate precise clock signals for external peripherals, and which pins are involved?
Yes, the M30621FCMGP#U3 can generate precise clock signals via its two independent clock generation circuits: the main oscillator (XIN/XOUT pins) supports 1–16 MHz crystals/resonators, while the sub-oscillator (XCIN/XCOUT pins) supports 32.768 kHz watch crystals. Both circuits include built-in feedback resistors, eliminating external components - details are in Section 35 of the M16C/62A Group datasheet.
What are the key differences between the M30621FCMGP#U3 and the M30622MCA-XXXGP mask ROM variant?
The M30621FCMGP#U3 is a flash memory version with 256 KB program storage and field-programmability, whereas the M30622MCA-XXXGP is a mask ROM variant with 128 KB fixed firmware and no reprogrammability. Both share identical 100P6Q-A packaging, 20 KB RAM, and peripheral sets (ADC, DAC, timers, DMAC), but only the flash version supports in-system programming and debug via on-chip bootloader - per Table 1.1.2 and Figure 1.1.5 of the M16C/62A Group documentation.
