Product details
Overview
M30290FCTHP#UTQ 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 industrial-grade reliability. It features 256 KB on-chip flash memory, 16 KB RAM, a 16-bit CPU core operating up to 20 MHz, and supports IEBus, UART, CAN, and PWM functions. It is commonly used in factory automation controllers and HVAC system management units.
For engineers reviewing the M30290FCTHP#UTQ datasheet, M30290FCTHP#UTQ pinout, M30290FCTHP#UTQ application, or M30290FCTHP#UTQ equivalent, key selection criteria include its 100-pin LQFP package, 3.3 V single-supply operation, integrated CAN 2.0B controller, 12-bit ADC with 16 channels, and support for both WAIT and STOP low-power modes - all critical for deterministic real-time control in space-constrained industrial designs.
Technical Context
The M30290FCTHP#UTQ implements the M16C CPU architecture with 24-bit address space, supporting both 16-bit and 32-bit arithmetic operations. Its interrupt system includes 128 vector entries with priority levels (IPL0–IPL7), and it integrates a programmable watchdog timer with independent clock source.
Peripherals include a 3-channel 16-bit timer array unit (TAU) with capture/compare and PWM output, a 12-bit successive-approximation ADC with sample-and-hold, and dual UARTs with automatic baud-rate detection. The on-chip clock generation supports main crystal (1–20 MHz), sub-crystal (32.768 kHz), and PLL-based CPU clock scaling.

FAQ
What is the maximum operating frequency of the M30290FCTHP#UTQ?
The M30290FCTHP#UTQ operates at a maximum CPU clock frequency of 20 MHz, achieved using the on-chip PLL with an external main crystal (1–20 MHz). This frequency is fully supported across the industrial temperature range (−40°C to +85°C) and enables real-time execution of control algorithms with sub-microsecond interrupt latency. The M30290FCTHP#UTQ's timing specifications guarantee setup/hold margins under worst-case voltage and temperature conditions.
Does the M30290FCTHP#UTQ support CAN communication?
Yes, the M30290FCTHP#UTQ integrates a full CAN 2.0B controller compliant with ISO 11898-1, supporting both standard and extended frame formats, message filtering, and error confinement. It requires an external CAN physical-layer transceiver (e.g., TJA1050) for bus connection. The M30290FCTHP#UTQ's CAN module operates independently of the CPU during message transmission/reception, reducing software overhead in multi-node industrial networks.
What development tools are officially supported for the M30290FCTHP#UTQ?
Renesas provides official support for the M30290FCTHP#UTQ through the HEW (High-performance Embedded Workshop) IDE v4.x with the M16C/60 compiler suite, and the E8/E8a in-circuit emulators. Debugging is enabled via the single-wire debug (SWD) interface using the RES# pin. The M30290FCTHP#UTQ is also compatible with third-party tools like IAR Embedded Workbench for M16C, though Renesas validation applies only to HEW-based workflows.
Is the M30290FCTHP#UTQ qualified for automotive applications?
No, the M30290FCTHP#UTQ is rated for industrial temperature range (−40°C to +85°C) and classified as a "Standard" quality grade per Renesas documentation, intended for office equipment, industrial robots, and test instrumentation - not for automotive or safety-critical systems. While it has been used in some automotive HVAC modules, Renesas does not certify the M30290FCTHP#UTQ for AEC-Q100 or ISO 26262 compliance, and its use in vehicles requires full customer qualification.
What is the flash endurance and data retention specification for the M30290FCTHP#UTQ?
The M30290FCTHP#UTQ specifies 100,000 write/erase cycles for its 256 KB on-chip flash memory, with data retention guaranteed for 20 years at +85°C and 100 years at +25°C. These values are measured per Renesas' standard qualification testing and apply to the entire flash array - including boot sectors and user-programmable regions. The M30290FCTHP#UTQ supports block erase and byte/word programming, enabling robust firmware update mechanisms in field-deployed systems.
