1 / 81 page  R EM6812 Copyright © 2005, EM Microelectronic-Marin SA 1 www.emmicroelectronic.com Ultra Low Power 8-bit FLASH Microcontroller Description The EM6812 is designed to be battery operated for extended lifetime applications. Brownout and powercheck functions ensure reliable operation at or near undervoltage conditions, offering greater reliability in complex operation modes. Each of the 16 I/Os is freely programmable and the microcontroller has a dual quartz and trimmable RC oscillator up to 10MHz. It has an 8-bit RISC architecture specially designed for very low power consumption. With 2 clocks per instruction, EM6812 executes up to 2.5 MIPS at 5MHz and achieves an astonishing 2200 MIPS/Watt. Features Green mold / leadfree package True low current: 120 µA active mode @ 3V, 1MHz 6 µA standby mode, RC on 0.8 µA standby mode, RC off 0.16 µA sleep mode Up to 2.5 MIPS at 5MHz On-chip brownout detection Powercheck functions at start-up 8-level Supply Voltage Level Detection (SVLD) Fast wake-up from standby mode 16 fully configurable I/Os Input / Output Pull-up, Pull-down CMOS, N-channel open drain 6 high currents outputs, up to 20 mA Wide supply voltage range 2 V – 5.5 V Flash read monitor (allows save instruction execution at lowest voltages) Dual mode quartz and RC oscillators: 1 MHz – 10 MHz RC 32768 Hz crystal or external clock source 8-bit CoolRISC architecture 16 registers 2 clock per instruction 8x8bit hardware multiplier Power-On-Reset and watchdog Various Flash memory size: 2k x 22 bit (5.6k Byte) 4k x 22 bit (11.2k Byte) 8k x 22 bit (22.5k Byte) Fully static 512B or 256B RAM, Low power 12B RAM, Dual port 4B RAM Internal and external interrupts Frequency generator PWM functions 8/16-bit timers Prescaler: 10-bit RC divider 15-bit crystal divider SPI interface, UART programmable by software Small 24-pin TSSOP and SO packages (leadfree) CoolRISC 8-bit CR816L 16 registers Hardware multiplier Power Supply & Voltage Regulator Power On Reset Brownout S upply Voltage L evel Detector 8-level FLASH 22.5 kByte 11.2 kByte 5.6 kByte RAM 512x8 bit Prescaler 1 Prescaler 2 RC 1-10MHz Low Power RAM 12x8 bit Dual Port RAM 4x8 bit Crystal 32kHz Watchdog IRQ 4 x 8 bit (2 x 16 bit) Timer PORT A Pull-up/-down, Edge, Debounce PORT B SPI, soft UART, PWM, Frequency generator SECURITY CORE & MEMORY CLOCK & TIMING I/Os Block Diagram Tools & Services Easy to use emulator with full debug functions, full peripheral integration, C-compiler Windows-based software programs Programmer from different vendors Dedicated team of engineers for outstanding support PB4 PB5 PB6 PB7 V REG V DD OSC OUT OSC IN PA7 PA6 PA5 PA4 EM6812 TSSOP-24 SO-24 Package (top view) PB3 PB2 PB1 PB0 N.C.
