MC9S08PT32AVLF

The MC9S08PT32AVLF from NXP Semiconductors is an 8-bit microcontroller based on the S08 core, designed for versatile embedded applications. It offers up to 60 KB of flash memory for program storage and 256 bytes of EEPROM for data retention, alongside 4096 bytes of RAM.

This microcontroller supports a bus frequency of up to 20 MHz and operates within a voltage range of 2.7 V to 5.5 V. Its operating temperature spans from -40 °C to 105 °C, ensuring reliability in diverse environmental conditions. Key features include multiple power-saving modes, an internal clock source with frequency-locked-loop (FLL) control, and system protection mechanisms like a watchdog timer and low-voltage detection.

Integrated peripherals include a 12-bit Analog-to-Digital Converter (ADC) with 16 channels, multiple Flex Timer Modules (FTM), Inter-Integrated Circuit (I2C) and Serial Peripheral Interface (SPI) modules, and Serial Communication Interface (SCI/UART) modules. It also features an Analog Comparator (ACMP) and a Touch Sensing Input (TSI) module supporting up to 16 electrodes.

The MC9S08PT32AVLF is suitable for applications requiring efficient processing, flexible I/O, and robust performance. Its design considerations include on-chip debugging support via a single-wire background debug interface.
