下面是关于EM78P156E芯片的主要性能特征介绍,我们提供给广大客户及其他各类技术工程师参考借鉴。
EM78P156E is an 8-bit microprocessor with low-power and high-speed CMOS technology. There is a 1K*13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM) within it. It provides a PROTECTION bit to prevent a user’s code from intruding as well as 7 OPTION bits to match the user’s requirements.
 
Because of the OTP-ROM, the EM78P156E offers users a convenient way to develop and verify their programs.Moreover, a user’s developed code can be programmed easily by an EMC writer.
perating voltage range: 2.2V~5.5V
Available in temperature range: 0°C~70°C
Operating frequency range: DC ~ 36MHz
Low power consumption:
* less than 1.6 mA at 5V/4MHz
* typical of 15 mA at 3V/32KHz
* typical of 1 mA during the sleep mode
1Kx13 bits on chip ROM
One security register to prevent the code in the OTP memory from intruding
One configuration register to match the user’s requirements
48x8 bits on chip registers (SRAM)
2 bi-directional I/O ports
5 level stacks for subroutine nesting
8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt
Two clocks per instruction cycle
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
8 pull-high pins
7 pull-down pins
8 open-drain pins
Two R-option pins
Package type: SOP, SOIC and DIP
99.9% single instruction cycle commands
