1 / 154 page  R EM6819 Copyright © 2009, EM Microelectronic-Marin SA 07 /09 – rev.D 1 www.emmicroelectronic.com Sub-1V (0.6V) 8bit Flash MCU DC-DC Converter, E 2PROM Description The EM6819 is designed to be battery operated for extended lifetime applications. Its large voltage range from 3.6V down to 0.9V makes it a perfect match for today’s demanding applications. Brownout and powercheck functions ensure reliable operation at or near undervoltage conditions, offering greater reliability in complex operation modes. Each of the 24 I/Os are freely programmable and the microcontroller has a dual quartz and trimmable RC oscillator up to 15MHz. It has an 8-bit RISC architecture specially designed for very low power consumption. With 2 clocks per instruction, the EM6819 executes up to 7.5 MIPS at 15MHz and achieves astonishing 4000 MIPS/Watt. Features Wide supply voltage range 0.9 V – 3.6 V Runs down to 0.6V with enabled DCDC and still 10mA load current True low current: typ 140uA at 3V, 1 MIPS Up to 7.5 MIPS at 15MHz DC-DC converter using just external coil and capacitor On-chip brownout detection PowerCheck functions at start-up 32 Voltage Level Detection on Supply or Input pin 3 terminal Operational Amplifier / Comparator ADC 10-bit, 8 channel Temperature sensor Voltage reference input/output Fast wake-up Up to 24 fully configurable I/Os Flash read monitoring system lowest voltages Dual clock mode, quartz and RC oscillators: o 2 MHz – 15MHz RC, pre-trimmed o Low freq RC Oscillator (8kHz) o 32768 Hz Xtal, 4MHz Resonator/Xtal, Ext Clock 8-bit CoolRISC architecture o 16 registers o 8*8bit hardware multiplier Power-On-Reset and watchdog GPNVM Memory o Sharing Instruction code and data Fully static 512 Byte RAM Internal and external interrupts Frequency generator 4 independent PWM outputs 8/16-bit timers Prescaler for RC and XTAL SPI interface Small size, Green mold / lead-free packages Tools & Services On chip debug system in the application ISP (In-system) programming C-compiler Windows-based software programs Programmer from different vendors Dedicated team of engineers for outstanding support Architecture Power Supply 0.9 – 3.6V DC-DC Up-Converter 2.1V, 2.5V, 2.9V, 3.3V Voltage Regulator Power On Reset BrownOut & Power Check Voltage Level Detector 32 – levels VSUP, PA, PC GPNVM (FLASH) 16.9 kByte Data Instruction Memory Memory Max 12 kB Max 6 kInstr Reset & wake-up Controller RC 8KHz Watch Dog IRQ & Event controller Crystal 32kHz Prescaler 2 10 stages Prescaler 1 15 stages for RTC GASP Debug-on-Chip ISP Monitor 2 wire & TM Timer1, Timer2 2x8 bit or 16 bit PWM , Freq Gen Input capure Output compare ADC 10 BIT 8 channels OPERTIONAL AMPLIFIER 3 terminals, PA, PC 8 BITS PORT A Pull-up, pull-down Interrupt, Capture Reset & Wake-up ADC, VLD, OPA,VREF Timer start & clock PWM, Signals 8 BITS PORT B SPI or soft UART PWM, signals GASP interface POWER MANAGEMENT & SECURITY MEMORIES & CORE Digital & Analog PERIPHERALS CLOCK & SYSTEM 8 BITS PORT C Pull-up, pull-down Interrupt,Capture ADC, VLD, OPA Timer start & clock PWM, Signals Crystal or Resonator 4MHz X1(optional) RC 2 MHz RC 15 MHz 32kHz / 4MHz Sleep Counter wake-up Timer3, Timer4 2x8 bit or 16 bit PWM , Freq Gen Input capure Output compare IO’s RAM 512 Bytes Fully static CoolRISC 8-bits CR816L 16 registers HW multiplier ROM-API Application subroutines PA[7:0] PB[5:0] PC[7:0] PB[7:6] TM Temp Sensor SPI 8 bits master or slave + DC-DC VREG Cvreg VSUP Cdcdc VSS VSSDC VSS2 VSUP2 Ldcdc Pinout (sample) Others include SO8, TSSOP16/20/28, QFN20/32 32 31 30 29 28 27 26 25 2 1 9 10 11 12 13 14 15 16 PB7 PA0 PC0 PA1 PC1 PA2 PC2 PA3 DCDC VSUP2 VSUP PB1 PB0 PC7 PA7 PA6 4 3 6 5 8 7 23 24 21 22 19 20 17 18 32 Lead QFN 5x5mm body EM6819 DCDC Typical Applications Metering Safety and Security devices Heat Cost Allocation Sensor Interfaces, Smoke detector Security Body care Sports Computer peripherals, Bluetooth chipset Wireless EM MICROELECTRONIC - MARIN SA |
