5 / 52 page EM78P156K 8-Bit Microcontroller with OTP ROM Product Specification (V1.3) 07.25.2012 • 1 (This specification is subject to change without further notice) 1 General Description The EM78P156K is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The device has an on-chip 1024 ×13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides a protection bit to prevent intrusion of user’s OTP memory code. Three Code option words are also available to meet user’s requirements. With enhanced OTP-ROM features, the EM78P156K 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. Users can avail of the ELAN Writer to easily program their development code. 2 Features CPU configuration • 1k × 13 bits on-chip ROM • 48 × 8 bits on-chip registers (SRAM, general purpose) • 5-level stacks for subroutine nesting • Less than 1.5 mA at 5V / 4MHz • Typically 15 µA at 3V / 32kHz • Typically 1 µA during Sleep mode I/O port configuration • 2 bidirectional I/O ports : P5, P6 • 12 I/O pins • Wake-up port : P6 • 5 Programmable pull-down I/O pins (P50 ~ P52, P60 ~ P63) • 6 programmable pull-high I/O pins (P60 ~ P67) • 6 programmable open-drain I/O pins (P60 ~ P67) • 2 programmable R-option pins • External interrupt : P60 Operating voltage range: • 2.1V ~ 5.5V at 0 ~ 70 (C (Commercial) • 2.3V ~ 5.5V at -40 ~ 85 (C (Industrial) Operating frequency range (base on 2 clocks): • Crystal mode: DC ~ 20MHz / 2clks @ 5V DC ~ 8MHz / 2clks @ 3V DC ~ 4MHz / 2clks @ 2.1V • ERC mode: DC ~ 2MHz / 2clks @ 2.1V • IRC mode: Drift Rate Internal RC Freq.
