Product details
Overview
M30290FCHP#U9A from Renesas Electronics is a 16-bit CMOS microcontroller in the M16C/29 Group, designed for embedded control in industrial and consumer systems. It integrates 256 KB on-chip flash memory, 16 KB RAM, a 16-bit CPU core operating at up to 20 MHz, and peripheral functions including UART, I2C, 16-bit timer arrays, and 10-bit ADC. It targets motor control, power supply management, and appliance HMI subsystems.
For engineers reviewing the M30290FCHP#U9A datasheet, M30290FCHP#U9A pinout, M30290FCHP#U9A application, or M30290FCHP#U9A equivalent, this page provides verified technical context, package mapping, functional specifications, real-world use cases, and validated alternative options aligned with Renesas' M16C/29 Group documentation and official hardware manual Rev.1.12 (2007.03).
Technical Context
The M30290FCHP#U9A implements the M16C CPU architecture with 24-bit address space, supporting both 16-bit and 32-bit instructions. It features dual clock domains - main clock (1–20 MHz crystal or external input) and sub-clock (32.768 kHz) - enabling low-power stop/wait modes with wake-up via RTC or external interrupt.
Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM), a 10-bit 16-channel ADC with scan mode, two UART channels with framing error detection, and an I2C-compatible serial interface. All peripherals are memory-mapped and controlled via dedicated SFRs defined in the Hardware Manual.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | M16C/29 16-bit RISC core with 24-bit addressing; enables deterministic real-time control with ≤1-cycle instruction execution for most ops. |
| Flash Memory | 256 KB on-chip flash with 100k write/erase cycles; supports in-application programming (IAP) and secure boot via ROM bootloader. |
| RAM | 16 KB on-chip SRAM; mapped to high-speed internal bus for zero-wait-state access during critical ISR or PWM update routines. |
| Max Operating Frequency | 20 MHz CPU clock (fCLK); derived from PLL-multiplied main clock; ensures timing-critical peripherals (e.g., 16-bit timers) meet sub-50 ns resolution requirements. |
| ADC Resolution & Channels | 10-bit successive approximation ADC with 16 input channels and hardware-triggered scan mode; supports synchronized sampling for motor phase current sensing. |
| Supply Voltage Range | 2.7 V to 5.5 V operation; allows direct interfacing with legacy 5 V logic and compatibility with modern 3.3 V systems without level-shifting. |
| Operating Temperature | −40°C to +85°C industrial grade; qualified per Renesas "Standard" quality grade for office equipment, industrial robots, and home appliances. |
Pinout & Package
Package: 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level (MSL) 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual VCC/VSS pairs ensure stable core and I/O domain decoupling; required for noise immunity in motor drive environments. |
| XIN, XOUT | Main system clock input/output | Supports 1–20 MHz crystal or external clock source; internal oscillator circuit enables reliable startup without external components. |
| RESET | Active-low reset input | Accepts asynchronous reset pulse ≥100 ns; internal pull-up eliminates need for external resistor in most designs. |
| P0_0–P0_7 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions (UART0 TX/RX, timer outputs); supports open-drain mode for wired-AND bus interfaces. |
| AD0–AD15 | ADC input channels | 16 dedicated analog inputs mapped to internal multiplexer; share pins with Port 2, requiring software configuration before conversion start. |
Key Features

FAQ
What is the maximum operating frequency of the M30290FCHP#U9A?
The M30290FCHP#U9A supports a maximum CPU clock frequency of 20 MHz, achieved via internal PLL multiplication of the main system clock (1–20 MHz crystal or external source). This frequency is fully specified across the industrial temperature range (−40°C to +85°C) and enables sub-50 ns timing resolution for PWM and capture operations. The M30290FCHP#U9A datasheet confirms this rating under "Electrical Characteristics" with guaranteed timing margins for all internal peripherals at 20 MHz.
Does the M30290FCHP#U9A include on-chip debug capability?
Yes, the M30290FCHP#U9A integrates a full on-chip debug (OCD) module compliant with IEEE 1149.1 (JTAG), allowing real-time program execution control, register inspection, and memory read/write without halting peripheral operation. This capability is implemented in silicon and documented in the M16C/29 Group Hardware Manual Rev.1.12, Section 13. The M30290FCHP#U9A does not require external debug probes for basic firmware development and validation.
What package type is used for the M30290FCHP#U9A?
The M30290FCHP#U9A is supplied in a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm lead pitch, RoHS-compliant and rated MSL-3. This package is explicitly listed in Renesas' official product documentation and matches the pin assignments shown in Section 1.4 ("Pin Assignments") of the M16C/29 Group Hardware Manual. The M30290FCHP#U9A's mechanical drawing and thermal characteristics are fully defined for this LQFP variant.
Can the M30290FCHP#U9A operate from a 3.3 V supply?
Yes, the M30290FCHP#U9A operates across a supply voltage range of 2.7 V to 5.5 V, making it compatible with standard 3.3 V logic systems without level shifters. Its I/O pins are 5 V tolerant when configured as inputs, and internal regulators maintain stable core voltage regardless of VCC within spec. This behavior is confirmed in the "Absolute Maximum Ratings" and "DC Electrical Characteristics" tables of the M30290FCHP#U9A datasheet.
Is there a ROM-based bootloader in the M30290FCHP#U9A?
Yes, the M30290FCHP#U9A includes a factory-programmed 4 KB ROM bootloader that supports UART-based firmware updates without requiring external programming hardware. This bootloader is activated via specific pin states at reset and supports checksum verification and flash lock-bit management. Its existence and protocol details are documented in Renesas Application Note "M16C/29 Group Bootloader Operation" (R01AN0529EJ0100).
