Freescale MC908QY8VDWE

HC088MHz8KB（8K x 8）

Overview

Description The MC68HC908QB8 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 Features include: • High-performance M68HC08 CPU core • Fully upward-compatible object code with M68HC05 Family • 5-V and 3-V operating voltages (VDD) • 8-MHz internal bus operation at 5 V, 4-MHz at 3 V • Trimmable internal oscillator – Software selectable 1 MHz, 2 MHz, or 3.2 MHz internal bus operation – 8-bit trim capability – ± 25% untrimmed – Trimmable to approximately 0.4%(1) • Software selectable crystal oscillator range, 32–100 kHz, 1–8 MHz, and 8–32 MHz • Software configurable input clock from either internal or external source • Auto wakeup from STOP capability using dedicated internal 32-kHz RC or bus clock source • On-chip in-application programmable FLASH memory – Internal program/erase voltage generation – Monitor ROM containing user callable program/erase routines – FLASH security(2) • On-chip random-access memory (RAM) • Enhanced serial communications interface (ESCI) module • Serial peripheral interface (SPI) module • 4-channel, 16-bit timer interface (TIM) module • 10-channel, 10-bit analog-to-digital converter (ADC) with internal bandgap reference channel (ADC10) • Up to 13 bidirectional input/output (I/O) lines and one input only: – Six shared with KBI – Ten shared with ADC – Four shared with TIM – Two shared with ESCI – Four shared with SPI – One input only shared with IRQ – High current sink/source capability on all port pins – Selectable pullups on all ports, selectable on an individual bit basis – Three-state ability on all port pins • 6-bit keyboard interrupt with wakeup feature (KBI) – Programmable for rising/falling or high/low level detect • Low-voltage inhibit (LVI) module features: – Software selectable trip point • System protection features: – Computer operating properly (COP) watchdog – Low-voltage detection with reset – Illegal opcode detection with reset – Illegal address detection with reset • External asynchronous interrupt pin with internal pullup (IRQ) shared with general-purpose input pin • Master asynchronous reset pin with internal pullup (RST) shared with general-purpose input/output (I/O) pin • Memory mapped I/O registers • Power saving stop and wait modes • MC68HC908QB8, MC68HC908QB4 and MC68HC908QY8 are available in these packages: – 16-pin plastic dual in-line package (PDIP) – 16-pin small outline integrated circuit (SOIC) package – 16-pin thin shrink small outline packages (TSSOP) Features of the CPU08 include the following: • Enhanced HC05 programming model • Extensive loop control functions • 16 addressing modes (eight more than the HC05) • 16-bit index register and stack pointer • Memory-to-memory data transfers • Fast 8 × 8 multiply instruction • Fast 16/8 divide instruction • Binary-coded decimal (BCD) instructions • Optimization for controller applications • Efficient C language support
