MC68HC908GR芯片解密以及FREESCALE系列其他典型的MC68HC芯片解密是目前龙人集团芯片解密研究所拥有成熟解密方案的典型优势解密项目。

下面是我们提供的关于MC68HC908GR芯片的主要性能特征介绍。

The MC68HC908GR16 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.

Features of the MC68HC908GR16 include:

High-performance M68HC08 architecture optimized for C-compilers

Fully upward-compatible object code with M6805, M146805, and M68HC05 Families

8-MHz internal bus frequency

Clock generation module supporting 32-kHz to 100-kHz crystals

FLASH program memory security(1)

On-chip programming firmware for use with host personal computer which does not require high voltage for entry

In-system programming (ISP)

System protection features:

– Optional computer operating properly (COP) reset

– Low-voltage detection with optional reset and selectable trip points for 3.3-V and 5.0-V operation

– Illegal opcode detection with reset

– Illegal address detection with reset

Low-power design; fully static with stop and wait modes

Standard low-power modes of operation:

– Wait mode

– Stop mode

Master reset pin and power-on reset (POR)

16 Kbytes of on-chip 100k cycle write/erase capable FLASH memory

1 Kbyte of on-chip random-access memory (RAM)

406 bytes of FLASH programming routines read-only memory (ROM)

Serial peripheral interface (SPI) module

Enhanced serial communications interface (ESCI) module

Two 16-bit timer interface modules (2-channel TIM1 and 2-channel TIM2)with

selectable input capture, output compare, and pulse-width modulation(PWM) capability on each channel

8-channel, 10-bit successive approximation analog-to-digital converter(ADC)

BREAK (BRK) module to allow single breakpoint setting during in-circuit debugging

Internal pullups on IRQ and RST to reduce customer system cost

Up to 37 general-purpose input/output (I/O) pins, including:

– 28 shared-function I/O pins

– Up to nine dedicated I/O pins, depending on package choice

Selectable pullups on inputs only on ports A, C, and D. Selection is on an

individual port bit basis. During output mode, pullups are disengaged.

High current 10-mA sink/source capability on all port pins

Higher current 20-mA sink/source capability on PTC0–PTC4

Timebase module (TBM) with clock prescaler circuitry for eight user

selectable periodic real-time interrupts with optional active clock source

during stop mode for periodic wakeup from stop using an external crystal

User selection of having the oscillator enabled or disabled during stop mode

8-bit keyboard wakeup port

5 mA maximum current injection on all port pins to maintain input protection

Available packages:

– 32-pin LQFP

– 48-pin low-profile quad flag pack (LQFP)
