The M30845FHGP#U3 operates at up to 32 MHz BCLK with VCC1 = 4.2–5.5 V and VCC2 = 3.0–VCC1. At reduced voltage (VCC1 = 3.0–5.5 V), it supports 24 MHz operation with 41.7 ns minimum instruction time. These ratings are specified in the official Renesas datasheet REJ03B0047-0121.
Does the M30845FHGP#U3 include a CAN controller, and what protocol version does it support?
Yes, the M30845FHGP#U3 integrates one CAN module compliant with CAN 2.0B specification, supporting both standard (11-bit) and extended (29-bit) identifier frames. This capability is documented in Table 1.1 and Section 1.2 of the M32C/84 Group datasheet.
How many A/D converter channels does the M30845FHGP#U3 provide, and what is its resolution?
The M30845FHGP#U3 includes a single 10-bit A/D converter with 26 input channels, as confirmed for the 100-pin package variant in Table 1.2 of the datasheet. Channel selection is software-controlled via the ADCH register, and conversion is triggered by software, timer, or external signal (e.g., ADTRG on P97).
What package type and pin count does the M30845FHGP#U3 use?
The M30845FHGP#U3 uses a 100-pin plastic LQFP package designated PLQP0100KB-A (14 × 14 mm, 0.5 mm pitch), as defined in the product numbering system (GP = 100P6Q-A) and confirmed in Figure 1.4 and Table 1.3 of the Renesas documentation.
Is the M30845FHGP#U3 compatible with IEBus and I²C interfaces?
Yes, the M30845FHGP#U3 supports both IEBus (1 channel) and I²C bus (2 channels) as part of its 5-channel serial I/O subsystem. IEBus functionality is implemented via dedicated pins (e.g., P60–P63), and I²C uses shared SCL/SDA pins across multiple serial channels, per Table 1.1 and Section 1.2.
