The MC9S08SE8 series MCUs are members of the cost-effective, high-performance S08 family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced S08 core and are available with a variety of modules, memory sizes, memory and package types.
8-bit HCS08 Central Processor Unit (CPU)
- Up to 20 MHz HCS08 (10 MHz internal bus frequency)
- HC08 instruction set with added BGND instruction
- Supports 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 µs (burst mode)
- 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 with a frequency-locked loop (FLL) controlled by internal or external reference
- Precision trimming of internal reference allows typical 0.2 percent resolution and 2 percent deviation over operating temperature and voltage
- Internal reference can be trimmed from 31.25 kHz to 38.4 kHz, allowing for up to 10 MHz FLL output
- Low-power oscillator module (XOSC) with software-selectable crystal or ceramic resonator range, 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz
22 I/O Pins, One Input-Only Pin and One Output-Only Pin
- Outputs 10 mA each, 60 mA max for package
- Software-selectable pull-ups on ports when used as inputs; internal pull-up on reset and interrupt request (IRQ) pin
- Software-selectable slew rate control and drive strength on ports when used as output
- 8-pin keyboard interrupt module with softwareselectable polarity on edge or edge/level modes
Ganged Output Option for PTB (5:2) and PTC (3:0)
- Allows single write to change state of multiple pins
- Provides option to tie multiple pins from different ports to same control registers
Multiple Serial Communication Options
- Serial communication interface module with option for 13-bit break capabilities and double-buffered transmit and receive
Analog-to-Digital Converter (ADC)
- 10-channel
- 10-bit
- Automatic compare function, software programmable for greater than, equal to or less than conditions
- Asynchronous clock source
- Temperature sensor
- Hardware triggerable using the RTC counter
- Low-power and high-speed options
Real-Time Counter (RTC)
- 8-bit modulus counter with binary or decimal-based prescaler
- Three software selectable clock sources
- 1 kHz internal low-power oscillator
- External clock and 32 kHz internal clock
Three Timer Modules
- Programmable 16-bit timer/PWM modules (TPM1 and TPM2)
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
- Security feature for flash and RAM
- Always-on power-on reset (POR) circuitry
Development Support
- Background debugging system
- On-chip in-circuit emulation (ICE) with real-time bus capture
