MC9S08QB4CTG Description

The MC9S08QB4CTG 16-pin TSSOP and 28-pin SOIC are pins compatible with the QE8 device as a subset of the QE family. The microcontroller MC9S08QB4CTG has low-power features such as two ultralow-power stop modes, new low-power run and wait for modes, 6 μs wake-up time, ultra-low-power external oscillator, and clock gating register to turn off clocks to unused peripherals.

The QB8 has an 8-channel, 12-bit resolution analog-to-digital converter and up to 8 KB of flash memory (ADC). The S08QB8 can still run at its maximum 20 MHz CPU speed when powered down to 1.8V. A real-time counter, analog comparator, an 8-channel keyboard interrupt module, an 8-bit modulo timer, and a 16-bit timer/pulse width modulator are all included in QB8, which is ideal for low-cost, battery-sensitive, portable, and low-power applications.

MC9S08QB4CTG Features

• Two ultra-low-power stop modes, one of which allows limited use of peripherals

• Allows continued application sampling in a reduced power state which extends battery life

• Allows use of all chip peripherals in a low-power state

• Enables faster execution out of stop modes

• New low-power run and wait modes

• 6 μs typical wake up time from stop mode

• Clock gating disables clocks to unused peripherals

• Provides flexibility to turn off individual modules

• Reduces power consumption
