EM78P301N数据手册Elan中文资料规格书

描述 Description

The EM78P301N is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The device has an on-chip 1k x 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.

特性 Features

CPU Configuration
• 1K x 13 bits on-chip ROM
• 80 bytes on-chip registers (SRAM)
• 8-level stacks for subroutine nesting
• Less than 1.5 mA at 5V/4MHz
• Typically 15 μA at 3V/32kHz
• Typically 2 μA during Sleep mode

I/O Port Configuration
• 3 bidirectional I/O ports: P5, P6, P7
• 12 I/O pins
• Wake-up port: P5
• 8 programmable pull-down I/O pins (P50~P57)
• 10 programmable pull-high I/O pins (P50~P57, P60, P67)
• 2 programmable open-drain I/O pins (P60, P67)
• 8 programmable high-sink current I/O pins (P50~P57, P60, P67)
• External interrupt: P60

Operating Voltage and Temperature Range
• 2.1V~5.5V at 0°C~70°C (Commercial Grade)
• 2.3V~5.5V at -40°C~85°C (Industrial Grade)

Operating Frequency Range
• Crystal Mode: DC~16MHz/2clks@4.5V; DC~8MHz/2clks@3V; DC~4MHz/2clks@2.1V
• ERC Mode: DC~2MHz/2clks@2.1V
• IRC Mode: 1MHz, 4MHz, 8MHz, 16MHz ±2%@25°C, 5V

All the four main frequencies can be trimmed by programming with four calibrated bits in the ICE300N / ICE300K Simulator. OTP is auto trimmed by ELAN Writer.

Fast set-up time requires only 0.8ms (VDD: 5V Crystal: 4 MHz, C1/C2: 15pF) in XT mode and 10µs in IRC mode (VDD: 5V, IRC: 4 MHz)

Peripheral Configuration
• 8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt
• 4 programmable level voltage detector (LVD): 4.5V, 4.0V, 3.3V, 2.2V
• Power-on reset (POR) and three programmable level voltage reset (LVR): 4.0, 3.5, 2.7V, 1.8V (Default)
• 8-channel Analog-to-Digital Converter with 12-bit resolution in Vref (2/3/4V) mode
• Two Pulse Width Modulation (PWM) with 10-bit resolution

Nine Available Interrupts
• TCC overflow interrupt
• Input-port status changed interrupt (wake-up from sleep mode)
• External interrupt
• ADC completion interrupt
• Low voltage detector interrupt
• PWM 1~2 period match interrupt
• PWM 1~2 duty match interrupt

Special Features
• Programmable free running watchdog timer (4.5ms:18 ms)
• Power down mode (Sleep mode)
• Power-on voltage detector available
• High EFT immunity (better performance at 4 MHz or below)
