The C167CRLMHAKXUMA2 from Cypress Semiconductor (now part of Infineon Technologies) is a sophisticated 16-bit ROMless microcontroller designed for demanding embedded applications requiring high performance and extensive peripheral integration. This IC belongs to the renowned C16xx series and features the powerful C166 core processor operating at 25MHz, making it suitable for real-time control applications where processing speed and deterministic response are critical.
As a ROMless microcontroller, this device addresses the design challenge of providing maximum flexibility for developers who need to implement custom memory configurations or use external program memory, allowing for larger code storage and easier firmware updates in production environments. The chip integrates 4K x 8 RAM for data handling and comes equipped with 111 I/O pins in a compact 144-pin P-MQFP (Plastic Metric Quad Flat Pack) surface mount package, providing extensive connectivity options while maintaining a reasonable footprint for space-constrained designs.
The microcontroller excels in connectivity with built-in CANbus support for automotive and industrial networking, EBI/EMI (External Bus Interface/External Memory Interface) for memory expansion, SPI for high-speed serial communication, and UART/USART for standard serial interfaces. It incorporates essential peripherals including Power-On Reset (POR) for reliable startup, Pulse Width Modulation (PWM) for motor control and power management applications, and a Watchdog Timer (WDT) for system reliability. The integrated 16-channel 10-bit analog-to-digital converter enables direct sensor interfacing without external components, while the external oscillator type allows designers to select optimal clock sources for their specific timing requirements.
Operating across an industrial temperature range of -40°C to 125°C with a supply voltage of 4.5V to 5.5V, this microcontroller is engineered for harsh environments found in automotive, industrial automation, motor control, and embedded control systems. The device is supplied in Tape & Reel packaging with a quantity of 2512 units, facilitating automated assembly processes in high-volume manufacturing.
Equivalent and alternative models within the C16xx family include the C167CR series variants with different memory configurations, the C167CS with integrated ROM, and pin-compatible derivatives like the C164CI and C165 series that offer similar architectures with varying peripheral sets and memory options, allowing designers to scale their solutions based on specific application requirements.
