7 / 110 page  EM78P350N 8-Bit Microprocessor with OTP ROM Product Specification (V 1.0) 09.14.2006 • 1 (This specification is subject to change without further notice) 1 General Description The EM78P350N is an 8-bit microprocessors designed and developed with low-power and high-speed CMOS technology. It has an on-chip 8K ×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 bits are also available to meet user’s requirements. With its enhanced OTP-ROM feature, the EM78P350N 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. User can avail of the ELAN Writer to easily program his development code. 2 Features CPU configuration • 8K×13 bits on chip ROM • 144×8 bits on chip registers (SRAM) • 8 level stacks for subroutine nesting • 4 programmable Level Voltage Detector (LVD) : 4.5V, 4.0V, 3.3V, 2.2V • 4 programmable Level Voltage Reset (LVR) : 4.0V, 3.5V, 2.7V, 1.8V (POR) • Less than 2.2 mA at 5V/4MHz • Typically 15 µA, at 3V/32kHz • Typically 1 µA, during sleep mode I/O port configuration • 4 bidirectional I/O ports : P5, P6, P7, P8 • 29 I/O pins • Wake-up port : P6 • 29 Programmable pull-down I/O pins • 29 programmable pull-high I/O pins • External interrupt : P52, P53 Operating voltage range: • OTP version: Operating voltage range: 2.1V~5.5V • Mask ROM version: Operating voltage range: 1.8V~5.5V Operating temperature range: -40~85℃ Operating frequency range: Main clock • Crystal mode: DC ~ 20MHz/2clks @ 5V; DC ~100ns inst. cycle @ 5V DC ~ 8MHz/2clks @ 3V;DC ~ 250ns inst. cycle @ 3V • ERC mode: DC ~ 16MHz/2clks @ 5V; DC ~ 125ns inst. cycle @ 5V DC ~ 8MHz/2clks @ 3V; DC ~ 250ns inst. cycle @ 3V • IRC mode: Oscillation mode : 4MHz, 8MHz, 1MHz, 455kHz Process deviation : Typ±3%, Max±5% Temperature deviation : ±10% (-40°C~85°C ) Sub clock Crystal: 32.768kHz Peripheral configuration • Serial peripheral interface (SPI) available • 8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt • 8-bit channels Analog-to-Digital Converter with 12-bit resolution • Three Pulse Width Modulation (PWM ) with 10-bit resolution • One pair of comparators or OP Eight available interrupts: • TCC overflow interrupt • Input-port status changed interrupt (wake-up from sleep mode) • Two External interrupt • ADC completion interrupt • PWM time period match completion interrupt • Comparator high/low interrupt • Serial I/O interrupt • Low voltage detect (LVD) Special features • Programmable free running watchdog timer • High ESD immunity • High EFT immunity • Power saving Sleep mode • Selectable Oscillation mode Package types: 28 pin DIP 600mil EM78P350NP 28 pin SOP 300mil EM78P350NM 28 pin SDIP 400mil EM78P350NK 28 pin SDIP 300mil EM78P350NAK 32 pin LQFP EM78P351NQ 32 pin SDIP 400mil EM78P351NK 32 pin DIP 600mil EM78P351NP 32 pin SOP l 300mil EM78P351NM 3 Pin Assignment |
