Overview
Features
Features
8-bit HCS08 Central Processor Unit (CPU)
- Up to 40 MHz HCS08 CPU (20 MHz bus frequency) for 50 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
- Fast, byte-writable programming, as fast as 20 µs/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 frequencylocked 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 16 MHz to 20 MHz FLL output
- Low-power oscillator module (XOSC)
- software selectable crystal or ceramic resonator range, 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz,
- supports external clock source input up to 40 MHz
Input/Output
- Up to 23 bidirectional lines
- 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 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 software selectable 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
- Drives up to 80 mA without risk of runaway code shorting
- Provides option to tie multiple pins from different ports to same control registers
- Safely drives multiple outputs
Multiple Serial Communication Options
- Serial communications interface module with option for 13-bit break capabilities and double-buffered transmit and receive
- Serial peripheral interface module and I2C bus module
Integrated Analog Peripherals
- 16-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
- Real-time-counter (RTC)
- 8-bit modulus counter with binary or decimal based prescaler
- External clock source for prescise time base, time-of-day, calendar or task scheduling functions
Three Timer Modules
- Programmable 16-bit timer/PWM modules (TPM1 and TPM2)
- 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
Development Support
- Background Debugging System
- On-Chip In-Circuit Emulation (ICE)
- Real-Time Bus Capture
