8-bit General Purpose GB MCUs | NXP Semiconductors

Overview

The MC9S08GB family are members of the cost-effective, high-performance S08 general purpose 8-bit microcontrollers. All MCUs in the family use the enhanced S08 core and are available with a variety of modules, memory sizes, memory types and package types.

The S08 family is an extension of the HC08 family, offering extended battery life with maximum performance down to 1.8-volt, high-performance flash and innovative development support.

Features

8-bit HCS08 CPU Core

Low-power technology
- Multiple power management modes, including 20 nA powerdown
- Optional autowake-up from Stop 2 or Stop 3 modes with internal timer typically requires only 300 nA additional current
- 1.8V operation
High performance when needed
- 50 ns minimum instruction cycle time down to 2.1V at 20 MHz bus
- 125 ns minimum instruction cycle time down to 1.8V at 8 MHz bus
C-optimized architecture with multiply and divide instructions

On-Chip Debug Interface

Single-wire background debug mode
On-chip trace buffer with nine flexible trigger modes and multiple hardware breakpoints
Nonintrusive emulation

Integrated Third-Generation Flash Memory

In-application reprogrammable
Self-timed, fast programming
- Can program 8 bits in 20 µs
- Fast Flash page erase
  - 20 ms (512B)
10K write/erase cycles minimum, 100K typical
15-year minimum data retention, 100 years typical
Internal program/erase voltage generation
Fine Flash granularity—512B Flash erase/1B Flash program
Flexible block protection and enhanced security

Internal Clock Generator

Programmable frequency-locked loop (FLL) generates 8 MHz to 40 MHz (for bus rates up to 20 MHz)
Post-FLL divider gives one of eight bus rate dividers
Trimmable with temperature and voltage compensation (<2 percent drift)
Provides multiple options for clock sources and in-application clock switching
- 32 kHz to 16 MHz external crystal/resonator
- Internal clock generator
- External clock

10-bit Analog-to-Digital Converter (ADC)

Eight-channel ADC
14 µs, 10-bit single conversion time

Timer with Eight Programmable Channels

Three-channel and five-channel, 16-bit timer systems
Each channel programmable for
- Input capture, output compare or buffered pulse-width modulator (PWM)
- PWM can be edge-or center-aligned
16-bit free-running or up/down (CPWM) count operation

Extensive Serial Communications

Dual asynchronous SCIs
- Flexible 13-bit module-based baud rate generators
- Double-buffered receive and transmit
Synchronous SPI
- Up to 5 Mbps
Inter-IC (I²C) bus
- Multicontroller operation
- 256 clock options

System Protection

Selectable low-voltage detect/reset at nominal 1.8V
Low-battery warning at nominal 2.4V or 2.1V
COP watchdog timer

56 Input/Output (I/O) Lines

Programmable pull-ups
High-current drivers
Eight keyboard interrupts
Controlled rise/fall times minimize noise
