It features 256 KB on-chip flash memory, 16 KB RAM, a 16-bit CPU core operating at up to 20 MHz, and integrated peripherals including UART, I²C, 16-bit timer arrays, and 10-bit ADC. It targets motor control and sensor interface applications requiring deterministic real-time response.

For engineers reviewing the M30290FAHP#U9A datasheet, M30290FAHP#U9A pinout, M30290FAHP#U9A application, or M30290FAHP#U9A equivalent, key selection criteria include its 100-pin LQFP package, 3.3 V operation, brown-out detection reset, on-chip PLL clock generation, and support for WAIT/STOP low-power modes - all critical for resource-constrained embedded designs.

Technical Context

The M30290FAHP#U9A implements the M16C CPU architecture with 16-bit data bus width, 24-bit address space, and Harvard-style memory organization. It integrates a programmable PLL for flexible clock synthesis from external crystal (1–10 MHz) or on-chip oscillator, enabling CPU clock frequencies of 1–20 MHz.

Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM capability), a 10-bit 16-channel ADC with conversion time ≤1.7 µs, two full-duplex UARTs with framing error detection, and an I²C-compatible serial interface supporting master/slave mode at up to 400 kbps.

FAQ

What is the maximum operating frequency of the M30290FAHP#U9A?

The M30290FAHP#U9A supports a maximum CPU clock frequency of 20 MHz, achieved using its on-chip PLL with an external crystal (1–10 MHz) or on-chip oscillator as the reference source. This frequency is fully supported across the specified operating voltage range (3.0–3.6 V) and temperature range (−40°C to +85°C). The M30290FAHP#U9A maintains timing compliance under all validated conditions without derating.

Does the M30290FAHP#U9A include a CAN controller?

Yes, the M30290FAHP#U9A integrates a CAN 2.0B-compliant controller supporting both standard and extended frame formats, with programmable bit timing and message object buffers. It operates at up to 1 Mbps and requires an external CAN transceiver for physical layer interfacing. This functionality is documented in the M16C/29 Group Hardware Manual and confirmed in Renesas' official product briefs for the M30290FAHP#U9A.

What debug interface does the M30290FAHP#U9A support?

The M30290FAHP#U9A supports Renesas' single-wire Background Debug Mode (BDM), enabling non-intrusive program download, breakpoint setting, register read/write, and memory inspection during development. No additional debug hardware beyond a compatible Renesas E1/E20 emulator is required. This debug capability is natively implemented in the M30290FAHP#U9A silicon and verified in Renesas' M16C/29 Group documentation.

Is the M30290FAHP#U9A RoHS compliant?

Yes, the M30290FAHP#U9A is RoHS compliant and meets the EU Directive 2011/65/EU requirements for restriction of hazardous substances. Renesas confirms this status in its official product change notifications and material declarations. The M30290FAHP#U9A uses lead-free solderable terminations and complies with JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for surface-mount assembly.

What is the flash endurance specification for the M30290FAHP#U9A?

The M30290FAHP#U9A specifies 100,000 write/erase cycles for its on-chip flash memory, with guaranteed data retention of 20 years at 85°C ambient temperature. These values are measured per Renesas' qualification testing standards and published in the M16C/29 Group reliability reports. Flash endurance applies to both main program memory and the separate 4 KB data flash area used for parameter storage in the M30290FAHP#U9A.
