General Description
The EM78P142 is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The series have an on-chip 2K×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 enhanced OTP-ROM features, the EM78P142 provide 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.
Features
■ CPU configuration
• 2K×13 bits on-chip ROM
• 80×8 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
• 3 programmable Level Voltage Reset
(LVR) : 4.0V, 3.5V, 2.4V
• 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
• 8 I/O pins
• Wake-up port : P5
• 5 programmable pull-down I/O pins
• 6 programmable pull-high I/O pins
• 1 programmable open-drain I/O pins
■ Operating voltage range:
• 2.1V~5.5V at 0°C~70°C (commercial)
• 2.3V~5.5V at -40°C~85°C (industrial)
■ Operating frequency range (base on 2 clocks):
• Crystal mode: DC ~ 16MHz, 4.5V;
DC ~ 8MHz, 3V; DC ~ 4MHz, 2.1V
• ERC mode: DC ~ 16MHz, 4.5V;
DC ~ 125ns inst. cycle, 4.5V
DC ~ 8MHz, 3V; DC ~ 250ns inst. cycle, 3V
• IRC mode
Oscillation mode: 16MHz, 4MHz, 1MHz, 455kHz
■ All the four main frequencies can be trimmed by programming with four calibrated bits in the ICE341N Simulator. OTP is auto trimmed by ELAN Writer.
■ Fast set-up time requires only 0.8ms (VDD: 5V Crystal: 4MHz, C1/C2: 30pF) in HXT2 mode and 10µs in IRC mode (VDD: 5V, IRC: 4 MHz)
■ Peripheral configuration
• Easily implemented IR (infrared remote control)
• 8-bit real time clock (TCC) with overflow interrupt
• 8-bit real time clock (TCCA, TCCC) and 16-bit real time clock (TCCB) with overflow interrupt
• 7-bit multi-channel Analog-to-Digital Converter with 12-bit resolution in Vref mode
■ Five available interrupts
• TCC, TCCA, TCCB, TCCC overflow interrupt
• Input-port status changed interrupt (wake up from sleep mode)
• ADC completion interrupt
• IR/PWM period match completion
• Low voltage detect (LVD) interrupt
■ Special Features:
• Programmable free running Watchdog Timer (4.5 ms : 18 ms)
• Power saving Sleep mode
• Selectable Oscillation mode
• Power-on voltage detector available (1.7V ± 0.1V)
• High EFT immunity (better performance at 4 MHz or below)
■ Package Type:
• 10 pin SSOP 150mil : EM78P142SS10J/S
