EM78P372N8-Bit Microcontroller1General DescriptionThe EM78P372N is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The device has 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 EM78P372N 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.2Features 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, 2.7V Less than 1.5 mA at 5V/4 MHz Typically 15 μA, at 3V/32kHz Typically 2 μA, during sleep mode 3 bidirectional I/O ports: P5, P6, P7 18 I/O pins Wake-up port : P5 8 programmable pull-down I/O pins 16 programmable pull-high I/O pins 8 programmable open-drain I/O pins 14 programmable high-sink current I/O pins External interrupt : P60Fast 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 8-bit multi-channel Analog-to-Digital Converter with 12-bit resolution in Vref mode One pair of comparator or OP(offset voltage: smaller than 10mV) Two Pulse Width Modulation (PWM) with 8-bit resolution I/O port configuration Ten available interrupts TCC overflow interrupt Input-port status changed interrupt (wake up from sleep mode) External interrupt ADC completion interrupt Comparator status change interrupt Low voltage detect (LVD) interrupt PWM1~2 period match interrupt PWM1~2 duty match interrupt 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): Special Features: Programmable free running Watchdog Timer (4.5 ms : 18 ms) Power saving Sleep mode Power-on voltage detector available (1.9V ± 0.2V) High EFT immunity (better performance at 4 MHz or below) Crystal mode: DC ~ 16 MHz, 4.5V; DC ~ 8 MHz, 3V; DC ~ 4 MHz, 2.1V ERC mode: DC ~ 2 MHz, 2.1V; IRC mode Oscillation mode: 16 MHz, 4 MHz, 1 MHz, 8 MHz Internal RC Temperature Voltage Frequency (-40°C~85°C) (2.1V~5.5V) Process Total 4 MHz 16 MHz 8 MHz 1 MHz ±2% ±2% ±2% ±2% ±1% ±1% ±1% ±1% ±2% ±2% ±2% ±2% ±5% ±5% ±5% ±5% Drift Rate Package Type: 10-pin MSOP 118mil 10-pin SSOP 150mil 14-pin DIP 300mil 14-pin SOP 150mil 16-pin SOP 150mil 18-pin DIP 300mil 18-pin SOP 300mil 20-pin DIP 300mil 20 pin SOP 300mil 20 pin SSOP 209mil: : : : : : : : : :EM78P372NMS10J/S EM78P372NSS10J/S EM78P372ND14J/S EM78P372NSO14J/S EM78P372NSO16AJ/S EM78P372ND18J/S EM78P372NSO18J/S EM78P372ND20J/S EM78P372NSO20J/S EM78P372NSS20J/S All the four main frequencies can be trimmed byprogramming with six calibrated bits in the ICE300N Simulator.
