Product details
Overview
M30621FCTGP#U 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 (100P6Q-A) package. It features 96KB mask ROM, 5KB RAM, 10-bit A-D converter (8+2 channels), dual 8-bit D-A converters, and two-channel DMAC - optimized for real-time control in office equipment and industrial automation systems.
For engineers reviewing the M30621FCTGP#U datasheet, M30621FCTGP#U pinout, M30621FCTGP#U application, or M30621FCTGP#U equivalent, key selection criteria include its 100-pin QFP footprint, 5V supply operation at 16MHz (62.5ns instruction cycle), integrated UART/SIO peripherals, and support for memory expansion up to 1MB.
Technical Context
The M30621FCTGP#U implements the M16C/60 Series CPU core 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 crystals (XCIN/XCOUT), enabling flexible timing source selection across system designs.
It integrates 11 programmable 16-bit timers (TA0–TA4, TB0–TB5), five serial I/O channels (three UART/clock-synchronous, two clock-synchronous), and a CRC-CCITT calculation circuit - all mapped into a unified 1MB address space with dedicated SFR region (00000h–003FFh) and vector table placement (FFE00h–FFFFFh).

FAQ
What is the maximum operating frequency of the M30621FCTGP#U?
The M30621FCTGP#U operates at a maximum frequency of 16MHz when supplied with 4.2V–5.5V and using the XIN/XOUT clock circuit. At this frequency, its shortest instruction execution time is 62.5ns. The device also supports 10MHz operation down to 2.7V with software-inserted wait states, maintaining full functionality across both voltage/frequency points.
Does the M30621FCTGP#U support external memory expansion?
Yes, the M30621FCTGP#U supports external memory expansion up to 1MB using its multiplexed address/data bus (P20–P37, P40–P47) and four chip select outputs (CS0–CS3). The device provides ALE, RD, WR/BHE, and RDY signals to interface with standard SRAM, EPROM, or peripheral ICs - enabling flexible system architecture without requiring external glue logic.
How many analog input channels does the M30621FCTGP#U include?
The M30621FCTGP#U includes eight dedicated 10-bit analog input channels (AN0–AN7) on P100–P107, plus two extended channels (ANEX0/ANEX1) on P95/P96 - totaling 10 usable A-D inputs. All channels share a common reference (VREF) and analog supply (AVCC/AVSS), and conversion can be triggered by software, timer, or external signal (ADTRG).
Is the M30621FCTGP#U pin-compatible with other M16C/62A group members?
Yes, the M30621FCTGP#U uses the 100P6Q-A package and shares identical pinout with all M16C/62A group variants in the same package type (e.g., M30622MCA-XXXGP, M30624FGAGP#U5). Signal names, electrical characteristics, and functional pin mapping are fully consistent across the family - enabling drop-in replacement where memory and peripheral requirements align.
What development tools are supported for the M30621FCTGP#U?
Renesas provides the HEW (High-performance Embedded Workshop) IDE with C compiler and debugger support for the M16C/62A Group, alongside the E8 emulator for hardware debugging. Third-party tools including IAR Embedded Workbench for M16C are also qualified. No JTAG interface is present; debugging relies on the on-chip debug interface accessible via dedicated pins (e.g., P80–P84).
