Product details
Overview
M30291FATHP#U3AAE9 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 flash memory, 16 KB RAM, a 16-bit CPU core, on-chip debug support, and peripheral functions including UART, I2C, PWM timers, and 10-bit ADC. It operates at up to 20 MHz with supply voltage range of 2.7–5.5 V.
For engineers reviewing the M30291FATHP#U3AAE9 datasheet, M30291FATHP#U3AAE9 pinout, M30291FATHP#U3AAE9 application, or M30291FATHP#U3AAE9 equivalent, key selection criteria include flash endurance (10,000 write/erase cycles), operating temperature range (−40°C to +85°C), I/O drive capability (±20 mA per port), and compatibility with Renesas' M16C development tools and C compiler suite.
Technical Context
The M30291FATHP#U3AAE9 implements the M16C CPU architecture with 16-bit data bus and 24-bit address space, supporting both little-endian and big-endian data access modes. It features dual clock domains - main clock (up to 20 MHz) and sub-clock (32.768 kHz) - enabling low-power real-time operation via stop/wait modes and brown-out detection reset.
Peripheral integration includes three 16-bit timer/counters with capture/compare/PWM output, one serial interface (UART/SIO), one I2C-compatible interface, and a 10-channel 10-bit successive-approximation ADC with internal reference. All peripherals are memory-mapped and controlled via dedicated SFRs with interrupt vectoring support.

FAQ
What is the maximum operating frequency of the M30291FATHP#U3AAE9?
The M30291FATHP#U3AAE9 supports a maximum main clock frequency of 20 MHz, delivering approximately 16.7 million instructions per second (MIPS) under typical conditions. This frequency is achievable using an external crystal connected to XT1/XT2 pins or an external clock source applied to the EXTAL pin. The device also supports PLL multiplication for internal clock scaling, though the final CPU clock remains capped at 20 MHz per its electrical specifications.
Does the M30291FATHP#U3AAE9 include on-chip debug capability?
Yes, the M30291FATHP#U3AAE9 integrates a single-wire debug (SWD) interface compliant with Renesas' E8/E8a debug protocol. This allows full non-intrusive debugging - including breakpoints, watchpoints, register inspection, and real-time memory access - without halting peripheral operation. Debug access requires the Renesas E8 emulator and associated CS+ or e2 studio IDE, and no external debug header is needed beyond the SWDIO and SWCLK pins.
What is the flash endurance specification for the M30291FATHP#U3AAE9?
The M30291FATHP#U3AAE9 specifies 10,000 write/erase cycles for its 256 KB on-chip flash memory, validated under standard industrial temperature and voltage conditions. Each sector can be erased independently, and programming is performed in byte, word, or block mode. Flash write operations require execution from RAM or protected ROM regions, and all writes must follow the sequence defined in the M16C/29 Group Hardware Manual section 3.3.2.
Can the M30291FATHP#U3AAE9 operate from a 3.3 V supply?
Yes, the M30291FATHP#U3AAE9 operates across a supply voltage range of 2.7 V to 5.5 V, fully supporting 3.3 V nominal systems. At 3.3 V, all I/O pins maintain full ±20 mA drive strength and TTL/CMOS-compatible logic thresholds. Internal regulators provide stable core voltage, and the ADC reference can be configured to use either AVCC or an internal 2.5 V bandgap source - ensuring consistent 10-bit conversion accuracy regardless of supply variation within spec.
Is the M30291FATHP#U3AAE9 qualified for automotive applications?
No, the M30291FATHP#U3AAE9 is classified as a "Standard" quality grade device per Renesas' product categorization, intended for industrial, office, and consumer equipment - not automotive or safety-critical systems. It lacks AEC-Q100 qualification, extended temperature screening (−40°C to +125°C), or fault-tolerant design features required for automotive ECUs. For automotive use, Renesas recommends the RL78/F1x or RH850 families instead.
