General Description The EM78P259N is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The device has an on-chip 2Kx13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides a protection bit to prevent i*usion of users code. Three Code option words are also *ailable to meet users requirements. With its enhanced OTP-ROM feature, the EM78P259N provides a convenient way of developing and verifying users programs. Moreover, this OTP device offers the advantages of easy and effective program updates, using development and programming tools. User can *ail of the ELAN Writer to easily program his development code. Features CPU configuration 2Kx13 bits on-chip ROM 80x8 bits on-chip registers (SRAM) 8-level stacks for subroutine nesting Less than 1.9 mA at 5V/4MHz Typically 15 uA, at 3V/32kHz Typically 1 uA, during Sleep mode I/O port configuration 3 bidirectional I/O ports : P5, P6, P7 17 I/O pins Wake-up port : P5 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: 2.3V~5.5V (Commercial) Operating voltage: 2.5V~5.5V (Industrial) Operating temperature range Operating temperature: 0°C ~70°C (Commercial) Operating temperature: -40°C ~85°C (Industrial) Operating frequency range Crystal mode: DC~20MHz/2clks @ 5V, DC~100ns inst. Cycle @ 5V DC~8MHz/2clks @ 3V, DC~250ns inst. Cycle @ 3V ERC mode: DC~16MHz/2clks @ 5V, DC~125ns inst. Cycle @ 5V DC~8MHz/2clks @ 3V, DC~250ns inst. Cycle @ 3V IRC mode: Oscillation mode : 4MHz, 8MHz, 1MHz, 455kHz Internal RC Frequency Drift Rate Temperature(-40°C ~80°C ) Voltage(2.3V~5.5V) Process Total 4MHz ±10% ±5% ±4% ±19% 8MHz ±10% ±6% ±4% ±20% 1MHz ±10% ±5% ±4% ±19% 455kHz ±10% ±5% ±4% ±19% All the four main frequencies can be trimmed by programming with four calibrated bits in the ICE259N Simulator. OTP is auto trimmed by ELAN Writer.
