5 / 58 page  EM78F651N 8-Bit Microcontroller Product Specification (V1.1) 10.20.2006 • 1 (This specification is subject to change without further notice) 1 General Description The EM78F651N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology and high noise immunity. It has an on-chip 1K ×13-bit Electrical Flash Memory and 128×8-bit in system programmable EEPROM. It provides three protection bits to prevent intrusion of user’s Flash memory code. Twelve Code option bits are also available to meet user’s requirements. With its enhanced Flash-ROM feature, the EM78F651N provides a convenient way of developing and verifying user’s programs. Moreover, this Flash-ROM device offers the advantages of easy and effective program updates, using development and programming tools. User can avail of the ELAN Writer to easily program his development code. 2 Features CPU configuration • 1K×13 bits on chip ROM • 80×8 bits on chip registers (SRAM) • 128 bytes in-system programmable EEPROM *Endurance: 100,000 write/erase cycles • More than 10 years data retention • 5-level stacks for subroutine nesting • Less than 2 mA at 5V/4MHz • Typically 20 µA, at 3V/32kHz • Typically 2 µA, during sleep mode I/O port configuration • 2 bidirectional I/O ports • Wake-up port : P6 • 8 Programmable pull-down I/O pins • 8 programmable pull-high I/O pins • 8 programmable open-drain I/O pins • External interrupt : P60 Operating voltage range: • Operating voltage: 2.2V~5.5V at -40°C ~85°C (Industrial) Operating frequency range (base on two clocks): • Crystal mode: DC ~ 20MHz @ 5V DC ~ 8MHz @ 3V DC ~ 4MHz @ 2.2V • ERC mode: DC ~ 16MHz @ 5V DC ~ 8MHz @ 3V DC ~ 4MHz @ 2.2V • IRC mode: DC ~ 16MHz @ 4.5V~5.5V DC ~ 4MHz @ 2.2V~5.5V Three available interrupts: • TCC overflow interrupt • Input-port status changed interrupt (wake-up from sleep mode) • External interrupt Peripheral configuration • 8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt • Power down (Sleep) mode *Vdd power monitor and supports low voltage detector interrupt flag • 4 programmable Level Voltage Detector (LVD) • Three security registers to prevent intrusion of Flash memory codes • One configuration register to accommodate user’s requirements • 2/4/8/16 clocks per instruction cycle selected by code option Single instruction cycle commands Four Crystal range in Oscillator Mode Crystal Range Oscillator Mode 20MHz ~ 6MHz HXT 6MHz ~ 1MHz XT 1MHz ~ 100kHz LXT1 32.768kHz LXT2 Programmable free running watchdog timer Package type: • 14-pin DIP 300mil : EM78F651NAPxS/xJ • 14-pin SOP 150mil : EM78F651NAMxS/xJ • 16-pin DIP 300mil : EM78F651NABPxS/xJ • 16-pin SOP 300mil : EM78F651NABMxS/xJ • 18-pin DIP 300 mil : EM78F651NCPxS/xJ • 18-pin SOP 300mil : EM78F651NCMxS/xJ • 20-pin DIP 300mil : EM78F651NDPxS/xJ • 20-pin SSOP 209mil : EM78F651NDKMxS/XJ Green products do not contain hazardous substances. |
