The MC9S08QA4 series are members of the cost-effective, high-performance S08 family of 8-bit microcontroller units featuring 1.8 to 3.3-volt operation, on-chip memory, two very low-power stop modes and low-voltage detection with reset or interrupt. The S08 core delivers a 40 MHz core speed and 20 MHz bus speed.

Features

8-bit HCS08 Central Processor Unit (CPU)

Up to 20 MHz HCS08 CPU (10 MHz bus frequency) for 100 ns minimum instruction time
HC08 instruction set with added BGND instruction
Support for up to 32 interrupt/reset sources

Integrated Third-Generation Flash Memory and RAM

Embedded flash that is in-application reprogrammable over the full operating voltage and temperature range with a single power supply
Extremely fast, byte-writable programming; as fast as 20 us/byte
Up to 100,000 write/erase cycles at typical voltage and temperature (10k minimum write/erase)
100 years typical data retention (15 years minimum)

Flexible Clock Options

Internal clock source (ICS) module containing a frequency-locked loop (FLL) controlled by internal or external reference
Precision trimming of internal reference allows typical 0.1 percent resolution and +0.5 percent to -1 percent deviation over operating temperature and voltage
Internal reference can be trimmed from 31.25 kHz to 39.065 kHz, allowing for 8 MHz to 10 MHz FLL output

Input/Output (I/O) Lines

4 Bidirectional Input/Output (I/O) Lines
One Input Only and One Output Only Line
Outputs 10 mA each, 60 mA max for package
Software selectable pull-ups on ports when used as input
- internal pull-up on reset
- interrupt request (IRQ) pin
Software selectable slew rate control and drive strength on ports when used as output
4-pin keyboard interrupt module with software selectable polarity on edge or edge/level modes

Integrated Analog Peripherals

4-ch., 10-bit analog-to-digital converter (ADC)
Automatic compare function, software programmable for greater than/equal to or less than conditions
Asynchronous clock source
Temperature sensor
Internal bandgap reference channel
Hardware triggerable using the RTI counter
Low-power and high-speed options

Analog comparator module (ACMP)

Option to compare to internal reference
Option to route comparator output directly to pin
Output can be optionally routed to TPM module as Input capture trigger

Two Timer Modules

Programmable 16-bit timer/PWM module (TPM)
8-bit modulo timer module (MTIM) with 8-bit prescaler

System Protection

Watchdog computer operating properly (COP) reset with option to run from dedicated 1 kHz internal clock source or bus clock
Low-voltage detection with reset or interrupt
Illegal opcode detection with reset
Flexible block protection
Security feature for flash and RAM
Always-on power-on reset (POR) circuitry
