CGM Flash MCU with OCDS

The device is a Flash Memory 8-bit high performance RISC architecture microcontroller device
with Continuous Glucose Meter (CGM) AFE module that specifically designed for Glucose Meter
applications. 

 

For memory features, the Flash Memory offers users the convenience of Flash Memory
multi-programming features. Other memory includes an area of RAM Data Memory as well as an
area of true EEPROM memory for storage of non-volatile data such as serial numbers, calibration
data etc. By using the In Application Programming technology, users have a convenient means to
directly store their measured data in the Flash Program Memory as well as having the ability to
easily update their application programs.

 

Analog features include a multi-channel 24-bit Delta Sigma A/D converter, four 12-bit D/A
converters, three internal operational amplifiers and one comparator. Multiple and extremely flexible
Timer Modules provide timing, pulse generation and PWM generation functions. Communication
with the outside world is catered for by including fully integrated SPI, UART and I2
C interface
functions, three popular interfaces which provide designers with a means of easy comminucation
with external peripheral hardware. Protective features such as an internal Watchdog Timer and
Low Voltage Reset coupled with excellent noise immunity and ESD protection ensure that reliable
operation is maintained in hostile electrical environments.

 

A full choice of internal high and low oscillator functions are provided including fully integrated
system oscillators which require no external components for their implementation. The ability to
operate and switch dynamically between a range of operating modes using different clock sources
gives users the ability to optimise microcontroller operation and minimise power consumption.

 

With regard to Glucose Meter applications, the device has integrated many of the functions required by these products. These include functions such as Internal Reference Voltage generator, Internal LDO, 24-bit Delta Sigma A/D converter, 12-bit D/A Converters and operational amplifiers, etc. The inclusion of flexible I/O programming features, 16-bit MDU, 16-bit Cyclic Redundancy Check function, Time Base functions along with many other features enhance the versatility of the device to suit for Glucose Meter applications.
