NXP MC9S08QG4CDTE Datasheet & Stock

The MC9S08QG4CDTE is an 8-bit microcontroller based on an enhanced HCS08 CPU architecture running at a maximum frequency of 20MHz with a 10MHz bus. It features 4KB of internal flash memory, 256 bytes of internal RAM, an 8-channel 10-bit Analog-to-Digital Converter (ADC), and 12 general-purpose I/O pins. The device includes peripherals such as an I2C bus module operating up to 100kbps and an SPI module. It has an internal clock source with a frequency-locked loop (FLL) that can be controlled by internal or external references, along with precision trimming of the internal reference for 0.2% resolution and 2% accuracy. The microcontroller supports watchdog reset with an optional dedicated 1kHz internal clock. It features an HC08 instruction set with BGND instruction, background debugging capabilities, breakpoint setting during in-circuit debugging, and a debug module with two comparators and nine trigger modes. Power-saving modes include Wait and three Stop modes. The internal clock source module includes an FLL, complemented by a low-power oscillator (XOSC), low-voltage detection with reset or interrupt, illegal opcode and address detection with resets, flash block protection, and multiple timers and interrupt modules. Additional features encompass software-controlled pull-ups, slew rate control, drive strength configuration on ports, and internal pull-ups on RESET and IRQ pins.
