MC68HC11KW1規(guī)格書詳情
INTRODUCTION
The MC68HC11KW1 8-bit microcontroller is a member of the M68HC11 family of HCMOS microcontrollers. It has 640 bytes of EEPROM and 768 bytes of RAM. Making use of a 100-pin TQFP package, a non-multiplexed expanded bus is a feature of this device. The main timer system includes three input captures, four output compares and a software selectable input capture or output compare. There are two additional 16-bit timers, each with three output compares and one software selectable input capture or output compare. Other major features of this device are: a 10-channel, 10-bit resolution A/D converter, four PWM timer channels, an SPI (serial peripheral interface) and an enhanced SCI (serial communications interface). In common with other family members, the MC68HC11KW1 also includes an 8-bit pulse accumulator circuit, a real time interrupt facility, and a computer operating properly watchdog system. This device is intended for use in expanded memory applications.
Features
? Low power, high performance M68HC11 CPU core with 4MHz internal bus frequency
? 768 bytes of RAM
? 640 bytes of byte-erasable EEPROM, with on-chip charge pump
? 448 bytes of boot ROM
? Up to 70 general purpose I/O lines, plus up to 10 input-only lines
? Non-multiplexed address and data buses, permitting direct access to the full 64K byte address map
? Memory expansion unit, with six address extension lines, allowing up to (for example) sixteen 32K byte banks of external memory to be addressed in either of two bank windows
? Four external chip selects
? 16-bit timer with 3/4 input captures and 5/4 output compares; pulse accumulator and COP watchdog timer
? Real-time interrupt circuit
? Two additional 16-bit timers, each with 3 output compares and one input capture or output compare (may be externally clocked, if required, for external event counter operation)
? SCI subsystem (NRZ type for compatibility with standard RS232 systems) with parity and a modulus prescaler
? SPI subsystem, with software selectable MSB/LSB first option and increased baud rate selection range
? 10-channel, 10-bit analog-to-digital converter
? Four 8-bit PWM timer channels
? Available in 100-pin TQFP package
