March 2007 Product Specification (V1.0) 03.20.2007 * iii Contents Specification Revision History Doc. Version 1.0 Revision Description Preliminary version. Date 2007/03/20 iv* Product Specification (V1.0) 03.20.2007 EM78P211/2N 8-Bit Microprocessor with OTP ROM 1 General Description EM78P211N and EM78P212N are 8-bit microprocessors designed and developed with low-power and high-speed CMOS technology. Each device in the series has as an on-chip 2Kx13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). Each provides a protection bit to prevent intrusion of user's OTP memory code. Two Code option bits are also available to meet user's requirements. With its enhanced OTP-ROM features, each device provides a convenient way of developing and verifying user's programs. Moreover, this OTP devices offer 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. 2 Features CPU configuration Drift Rate Internal RC Voltage Frequency Temperature Process (-40C+85C) (2.1V~5.5V) Total * 2Kx13 bits on-chip OTP-ROM * 80x8 bits on-chip registers (SRAM) * 8-level stacks for subroutine nesting * 3 programmable Level Voltage Reset (LVR) : 4.0V, 3.0V, 2.5V * Less than 1.5 mA at 5V/4MHz * Typically 15 A, at 3V/32kHz * Typically 2 A, during sleep mode I/O port configuration * 4 bidirectional I/O ports: P5, P6, P7 and P8 * Wake-up port : P6 * 22 I/O pins * 8 programmable pull-down I/O pins * 8 programmable pull-high I/O pins * 8 programmable open-drain I/O pins * 16 Programmable high sink current I/O pins * 8 Programmable high drive current I/O pins * External interrupt : P77, P71 Operating voltage range: * OTP version: Operating voltage range: 2.1V~5.5V (commercial) Operating voltage range: 2.3V~5.5V (industrial) Operating temperature range: Operating temperature range: 0C~70C (commercial) Operating temperature range: -40C~85C (industrial) Operating frequency range * Crystal mode: DC~12MHz/2 clks @ 4.0V; DC~166ns inst. cycle @ 4.0V DC ~ 8MHz/2 clks @ 3V; DC~250ns inst.
