芯片简介

Integrated Glucose Meter IC for Medical Applications
Device Description Ernie is a highly integrated glucose meter system on chip (SoC) specifically designed for the commercial and home medical markets.
Ernie contains a high performance 32-bit wide ARM M0 core with 160kB of
flash RAM and 8kB of SRAM. A real time clock (RTC), 12MHz RC oscillator,
32kHz sleep mode clock, 10kHz auxiliary clock, and watchdog timer are all
fully integrated on die for high performance, low power design.
The high performance analog front end (AFE) consists of a state of the art
16-bit sigma-delta ADC and two 14-bit DACs which together allow for fast,
highly precise chemical measurements with low calibration requirements.
Ernie includes integrated power management and is capable of running
entirely off either a 3V battery or the integrated USB port. An integrated
charge pump is capable of generating 4.5V from the battery and supplies
power to the LCD. No other components are required for power regulation
of the IC, creating an efficient, low cost design.
Ernie integrates multiple interface options. It can drive up to 120 display
elements in a 4 x 30 LCD segment display for feature-rich meaurement
readouts. Ernie also includes a USB 1.1 serial interface supporting control,
bulk, and interrupt transfers so that data can be stored and downloaded at
a later time.
Ernie easily interfaces to other discrete ICs through standardized UART, I2C
or SPI interfaces and provides 18 GPIO controls to interface with other on-
board components.
Ernie is pre-certified in medical devices and is currently available in mass
production quantities.
