- 14-lead packages : em78p153s
- operating voltage range : 2.3v~5.5v
- available in temperature range: 0°c~70°c
- operating frequency range (base on 2 clocks):
* crystal mode: dc~20mhz at 5v, dc~8mhz at 3v, dc~4mhz at 2.3v.
* erc mode: dc~4mhz at 5v, dc~4mhz at 3v, dc~4mhz at 2.3v. - low power consumption:
* less then 1.5 ma at 5v/4mhz
* typical of 15 µa, at 3v/32khz
* typical of 1µa, during the sleep mode - 1024 x 13 bits on chip rom
- built-in calibrated irc oscillators (8mhz, 4mhz, 1mhz, 455khz )
- programmable prescaler of oscillator set-up time
- one security register to prevent the code in the otp memory from intruding
- one configuration register to match the user’s requirements
- 32× 8 bits on chip registers (sram, general purpose register)
- 2 bi-directional i/o ports
- 5 level stacks for subroutine nesting
- 8-bit real time clock/counter (tcc) with selective signal sources and trigger edges,
- and with overflow interrupt
- power down mode (sleep mode)
- three available interruptions
* tcc overflow interrupt
* input-port status changed interrupt (wake up from the sleep mode)
* external interrupt - programmable free running watchdog timer
- 7 programmable pull-high i/o pins
- 7 programmable open-drain i/o pins
- 6 programmable pull-down i/o pins
- two clocks per instruction cycle
- package type: 14 pins sop, dip
* 14 pin dip 300mil: em78p153sp
* 14 pin sop 150mil: em78p153sn - the transient point of system frequency between hxt and lxt is around 400khz.
