FAQ
What is the maximum operating frequency and supply voltage range for the M30835FJGP#U3?
The M30835FJGP#U3 operates at up to 32 MHz BCLK with a supply voltage of 4.2–5.5 V. At reduced speed (20 MHz), it supports 3.0–5.5 V (via VDC) or 3.0–3.6 V (not via VDC). This dual-voltage flexibility allows compatibility with both 5 V legacy systems and lower-power 3.3 V designs while maintaining full peripheral functionality in the M30835FJGP#U3.
Does the M30835FJGP#U3 support CAN communication, and what version is implemented?
Yes, the M30835FJGP#U3 integrates one CAN module compliant with the CAN 2.0B specification, supporting both standard (11-bit) and extended (29-bit) identifier formats at bit rates up to 1 Mbps. The M30835FJGP#U3 provides dedicated CANIN and CANOUT pins with internal level-shifting - eliminating need for external CAN transceivers in basic implementations, though external drivers are required for bus termination and ESD protection.
How many analog-to-digital converter channels does the M30835FJGP#U3 provide, and what is their resolution?
The M30835FJGP#U3 features two independent 10-bit A/D converters with a total of 26 input channels. These channels are distributed across multiple port pins (e.g., AN00–AN07 on P0, AN20–AN27 on P2, and KI0–KI3 on P104–P107), enabling simultaneous sampling of diverse analog sensors. The M30835FJGP#U3's ADC supports programmable sample-and-hold timing and conversion triggers from timers or external events - critical for synchronized multi-sensor acquisition.
What package type and pin count does the M30835FJGP#U3 use?
The M30835FJGP#U3 uses a 100-pin plastic LQFP package designated PLQP0100KB-A, measuring 14 mm × 14 mm with 0.5 mm lead pitch. This RoHS-compliant package supports standard reflow soldering and provides 87 general-purpose I/O pins plus 1 dedicated input pin - matching the pinout defined in Renesas' M32C/83 Group documentation for 100-pin variants. The M30835FJGP#U3 is not pin-compatible with the 144-pin version.
Is the M30835FJGP#U3 supported by modern development tools and debug interfaces?
The M30835FJGP#U3 is supported by Renesas' legacy toolchain including the M3T-ICC compiler and E8/E8a debug emulators. While newer IDEs like e2 studio do not natively support M32C, third-party JTAG adapters (e.g., Segger J-Link with custom configuration) can provide basic flash programming and breakpoint debugging. Renesas maintains archived documentation and application notes for the M30835FJGP#U3 - ensuring continued maintainability for long-lifecycle industrial deployments.
