Renesas M30290T-80FPD

Overview

M30290T-80FPD from Renesas Electronics is a 16-bit CMOS microcontroller in the M16C/29 Group, designed for embedded control applications requiring integrated peripherals, low-power operation, and real-time responsiveness. It features 256 KB on-chip flash memory, 16 KB RAM, a 16-bit CPU core operating at up to 20 MHz, and supports industrial temperature range (−40°C to +85°C) in a 100-pin LQFP package.

For engineers reviewing the M30290T-80FPD datasheet, M30290T-80FPD pinout, M30290T-80FPD application, or M30290T-80FPD equivalent, key selection criteria include its 100-pin LQFP footprint, dual clock system (main/sub oscillators), integrated CAN controller (CAN v2.0B), 12-bit ADC with 16 channels, and support for on-chip debugging via JTAG interface.

Technical Context

The M30290T-80FPD implements the M16C CPU architecture with 16-bit data bus and 24-bit address space, enabling direct access to its full 256 KB flash and 16 KB RAM. Its peripheral set includes a 32-bit timer array unit (TAU), serial interface (UART/SIO), I²C-compatible interface, and a dedicated CAN controller supporting both standard and extended frames.

Power management is handled via three operational modes-Normal, Wait, and Stop-with brown-out detection reset and voltage detection interrupt. The device uses an on-chip PLL to generate internal clocks up to 20 MHz from external crystal (1–10 MHz) or ceramic resonator inputs, with independent clock domains for CPU and peripheral functions (f1, f2, f8, f32, fAD, fCAN0).

FAQ

What is the maximum operating frequency of the M30290T-80FPD?

The M30290T-80FPD operates at a maximum CPU clock frequency of 20 MHz, achieved via its on-chip PLL locked to an external crystal or resonator (1–10 MHz). This frequency is sustained across the full industrial temperature range (−40°C to +85°C) and supports deterministic instruction execution for time-critical control loops. The M30290T-80FPD's timing specifications guarantee setup/hold margins and interrupt latency compliance at this speed.

Does the M30290T-80FPD include an integrated CAN controller?

Yes, the M30290T-80FPD integrates a full CAN v2.0B controller compliant with ISO 11898-1:2003, supporting both standard and extended frame formats, message objects for hardware-based filtering, and baud rates up to 1 Mbit/s. It requires an external CAN transceiver (e.g., TJA1050 or SN65HVD230) for physical layer connection. The M30290T-80FPD's CAN module is independently clocked and supports automatic retransmission and error confinement.

What package type and pin count does the M30290T-80FPD use?

The M30290T-80FPD is housed in a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm lead pitch. This RoHS-compliant package supports standard surface-mount assembly processes and provides dedicated power/ground pairs for noise suppression. The M30290T-80FPD's pin assignment includes 80 general-purpose I/O lines, 16 ADC inputs, and dedicated CAN, UART, and clock signals - verified in Renesas Hardware Manual Rev.1.12.

Can the M30290T-80FPD operate from a single 5 V supply?

Yes, the M30290T-80FPD is specified for single 5 V ±10% operation (4.5 V to 5.5 V) across its entire industrial temperature range. It includes internal voltage regulation and brown-out detection circuitry that monitors VCC and asserts reset if voltage falls below user-configurable thresholds (4.0 V, 3.5 V, or 2.7 V). The M30290T-80FPD's power architecture eliminates need for external regulators in most 5 V industrial systems.

Is on-chip debug supported for the M30290T-80FPD?

Yes, the M30290T-80FPD supports full on-chip debugging via IEEE 1149.1 (JTAG) interface, enabling breakpoints, real-time variable watch, and flash programming without external emulators. Renesas' E8a and E20 debuggers are certified for use with the M30290T-80FPD. This capability is implemented in silicon and documented in the M16C/29 Group Hardware Manual - no additional firmware or boot ROM configuration is required to activate JTAG on the M30290T-80FPD.
