FAQ

What is the maximum operating frequency of the M30853FWGP#U3 CPU core?

The M30853FWGP#U3 CPU core achieves a minimum instruction execution time of 31.3 ns at 32 MHz BCLK, corresponding to a maximum operating frequency of 32 MHz under VCC1 = 4.2 V to 5.5 V conditions. At lower supply voltages (VCC1 = 3.0 V to 5.5 V), the device supports up to 24 MHz operation with 41.7 ns minimum execution time. This specification is confirmed in Renesas document REJ03B0046-0121, Table 1.2.

Does the M30853FWGP#U3 support in-system programming of its Flash memory?

Yes, the M30853FWGP#U3 supports in-system programming (ISP) of its 320 KB Flash memory using either 3.3 V ± 0.3 V or 5.0 V ± 0.5 V program/erase supply voltage. The device allows up to 100 program/erase cycles across the entire Flash space, and includes built-in erase verification logic. This capability enables field firmware updates without removing the IC from the PCB.

How many analog input channels does the M30853FWGP#U3 A/D converter support?

The M30853FWGP#U3 integrates a single 10-bit A/D converter supporting 26 analog input channels in the 100-pin LQFP package. This is explicitly documented in Table 1.2 of the Renesas datasheet REJ03B0046-0121. Channel mapping includes P00–P07 (AN00–AN07), P100–P107 (AN0–AN7), and P150–P157 (AN150–AN157), with additional ANEX0/ANEX1 on pins P95/P96.

What is the purpose of the P70 and P71 pins on the M30853FWGP#U3?

P70 and P71 on the M30853FWGP#U3 are N-channel open-drain output ports supporting multiple functions: P70 serves as TA0OUT, TxD2, SDA2, SRxD2, OUTC16, and INPC16; P71 serves as TA0IN, TB5IN, RxD2, SCL2, STxD2, OUTC17, and INPC17. Both require external pull-up resistors and are used for I²C communication, serial data exchange, and intelligent I/O waveform generation - as defined in Figure 1.4 and Table 1.4 of the official datasheet.

Is the M30853FWGP#U3 qualified for automotive applications?

Yes, the M30853FWGP#U3 is rated for −40°C to +85°C operating ambient temperature and belongs to the M32C/85T variant family - designated by Renesas as "High Quality" grade for transportation equipment including automobiles. Its dual CAN 2.0B modules, watchdog timer, and voltage detection circuit (optional) align with functional safety requirements for non-life-critical automotive subsystems such as body control and infotainment interfaces.
