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 intrusion of user””s code. three code option words are also available to meet user””s requirements.
with its enhanced otp-rom feature, the em78p259n provides a convenient way of developing and verifying user””s programs. moreover, this otp 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.

· 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
internal rc frequency	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.

peripheral configuration

· 8-bit real time clock/counter (tcca, tccc) and 16-bit real time clock/counter (tccb) with selective signal sources, trigger edges, and overflow interrupt
· 4-bit channel analog-to-digital converter with 12-bit resolution in vref mode
· easily implemented ir (infrared remote control) application circuit
· one pair of comparators or op
· tcc, tcca, tccb, tccc overflow interrupt
· input-port status changed interrupt (wake-up from sleep mode)
· external interrupt
· adc completion interrupt
· comparators status change interrupt
· ir/pwm interruptn
