Preliminary
GENERAL DESCRIPTION
The EM78Q156A/B is an 8-bit microprocessor with low-power, high speed CMOS technology. There are 1Kx13
bits Read Only Memory within it. It provides 13 Security bits and 5 One-time Programmable Option bits to protect
the OTP memory code from any external access as well as the user's options.
FEATURES
Operating voltage range : 2.5V ~ 6.5V
Available in temperature range:
Operation Speed : DC ~ 36 MHz
Low power consumption :
* <2mA, at 5V/4MHz
* 15
μ
A typical, at 3V/32KHz
* 1
μ
A typical, at sleep
1K x 13 Read Only Memory (OTP-ROM)
One Security Register is provided to protect the OTP memory code and to define user's ID code.
One Configuration Register is provided to meet the user's options.
13 special function registers.
48 x 8 on chip RAM.
2 bi-directional tri-state I/O ports (12 I/O pins).
5 level stack for subroutine nesting.
8-bit real time clock/counter (TCC) with selective signal sources and trigger edges, and with overflow
interrupt.
Programmable free running on-chip watchdog timer.
Two R-option pin.
Power down mode.
Input port change interrupt (wake-up), and external interrupt available.
99.9% single instruction cycle commands.
18 pin DIP, 20 pin SOIC.
Power on voltage detector.
