FAQ

What is the maximum operating frequency of the M30843FWGP#U5?

The M30843FWGP#U5 supports a maximum bus clock (BCLK) frequency of 32 MHz under VCC1 = 4.2–5.5 V conditions, achieving a shortest instruction execution time of 31.3 ns. At reduced supply voltages (3.0–5.5 V), it operates up to 24 MHz with 41.7 ns minimum cycle time. This performance is confirmed in Table 1.1 and Table 1.2 of the official Renesas REJ03B0047-0121 datasheet for the M32C/84 Group.

Does the M30843FWGP#U5 include an internal oscillator?

Yes, the M30843FWGP#U5 includes an on-chip oscillator as part of its four clock generation circuits, alongside main/sub crystal oscillator inputs and a PLL frequency synthesizer. The on-chip oscillator eliminates the need for an external crystal in applications where timing precision is secondary to cost and board space - a feature explicitly documented in Section 1.2 "Performance Overview" of the M32C/84 Group datasheet.

How many analog input channels does the M30843FWGP#U5 support?

The M30843FWGP#U5 supports 26 analog input channels for its 10-bit A/D converter, consistent with its 100-pin LQFP package configuration. This is specified in Table 1.2 ("M32C/84 Group Performance – 100-Pin Package") and confirmed in Figure 1.4's pin assignment diagram, where AN00–AN07, AN20–AN27, AN150–AN157, and KI0–KI3 collectively total 26 dedicated analog inputs.

Is the M30843FWGP#U5 pin-compatible with other M32C/84 family members?

The M30843FWGP#U5 shares the PRQP0100JB-A (100P6S-A) package and core peripheral mapping with other 100-pin M32C/84 variants like M30842FWGP#U5 and M30841FWGP#U5, but differs in Flash capacity (320 KB vs. 128/192 KB) and ROM configuration. Pin compatibility is maintained within the same package type, as verified in Table 1.3 and Figure 1.4 of the Renesas M32C/84 datasheet.

What development tools are supported for the M30843FWGP#U5?

The M30843FWGP#U5 is supported by Renesas' High-performance Embedded Workshop (HEW) IDE, the M32C/84 Target Board (M32C/84TB), and the E8 emulator. These tools provide full debug capability including flash programming, real-time trace, and peripheral register inspection - all validated for the M32C/84 Group in Renesas Application Note U15072EJ3V0AN00.
