Overview

HCS08

High-performance and low power, the HCS08 provides low power 1.8 V operation whilst maintaining a very respectable performance. The HCS08 family features multiple power management modes, including a 20 uA power-down mode.

Internally, the S08 instruction set is upward compatible with the 6805, with the addition of stack indexed addressing modes. (Instructions using the SP register have opcodes prefixed with the byte 0x9E). It has a single eight-bit accumulator, A, one eight-bit index register, X, or one sixteen-bit index registers, HX (formed from the combination of H and X registers), a condition code register, a 16-bit stack pointer, and a program counter. For compatibility with the 6805 which does not have an H register, the most significant byte of the HX register, H, is cleared during reset, and H is the only register not stacked automatically when entering any ISR (Interrupt Service Routine).

Some instructions treat the H and X registers as a combined 16-bit HX register. Unlike the 6805, the stack can be placed anywhere in memory using appropriate instructions. The standard method of programming or debugging the S08 family is via a standard 6-pin BDM interface. A wide variety of peripherals is available for different members and/or packages. SCI, SPI, 10-bit or 12-bit A/D, (C)PWM, Input Captures are common with most members, but no external bus is available.

RS08

The RS08 core is a reduced version of the S08 central processing unit (CPU) that has been specifically designed for small pin-count devices with under 16KB memory. Thirty percent smaller than the S08 CPU, it is more efficient and cost-effective for simple electro-mechanical devices that are migrating to fully solid-state electronic operation or portable devices that have evolved into smaller or even disposable versions.

Ideal for emerging applications like simple electro-mechanical devices that are migrating to fully solid-state operation, portable devices that have evolved into smaller or even disposable versions. Functions that are not required for such applications have been stripped from the S08 core and remaining operations have been enhanced to improve the efficiency of extremely small controllers.

Thirty percent smaller than the S08 core (can be shaken through a pepper shaker), the RS08 core has been streamlined by limiting the counter and address bus to 14 bits, replacing vectored interrupt capability with a global interrupt flag register and by removing: Stack point and H:X register along with the associated instructions and addressing modes, Multiply, Divide and binary-coded decimal instructions, Arithmetic logic shift operations (logical shifts and rotates have been retained), Bits in condition code register and associated conditional branching instructions.

The RS08 core deepens the Freescale 8-bit portfolio, and offers pin-for-pin compatible 8-bit and 32-bit devices that share peripherals and a common set of development tools. It also allows mechanical and electronic product developers to come up with the totallyunexpected—creating advanced, cost-effective electronic applications that have no precedent and disposable products with surprisingly sophisticated functionality.

Key Features

Standard features of the HCS08 family:

40-MHz HCS08 CPU (central processor unit)
HC08 instruction set with added BGND instruction
Background debugging system
Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module)
Debug module containing two comparators and nine trigger modes. Eight deep FIFO for storing change-of-flow addresses and event-only data. Debug module supports both tag and force breakpoints.
Support for up to 32 interrupt/reset sources
Power-saving modes: wait plus three stops
System protection features:
- Optional computer operating properly (COP) reset
- Low-voltage detection with reset or interrupt
- Illegal opcode detection with reset
- Illegal address detection with reset (some devices don’t have illegal addresses)

Standard features of the RS08 family:

Streamlined programmer’s model
Subset of HCS08 instruction set with minor instruction extensions
Minimal instruction set for cost-sensitive embedded applications
New instructions for shadow program counter manipulation, SHA and SLA
New short and tiny addressing modes for code size optimization
Maximum 16K bytes accessible memory space
Reset will fetch the first instruction from $3FFD
Low-power modes supported through the execution of the STOP and WAIT instructions
Debug and FLASH programming support using the background debug controller module
Illegal address and opcode detection with reset.
Eliminated vector fetch mechanism for interrupt and reset service
Eliminated RAM stacking mechanism for subroutine call
Single level hardware stacking for subroutine call
Stop wakeup through internal or external interrupt trigger
Hardware security feature to protect unauthorized access to the non-volatile memory (NVM) area
Debug and NVM program/erase support using single pin interface
