1. MSP430 Project

2. Group Members Charles Hornbuckle (group leader) Michael McCleary
James Millraney
John Kelly

3. Project Description Design a circuit using the MSP430F449PZ (MSP430)
Construct the circuit using a prefabricated board
Program the MSP430 with “tweaked” coding provided while implementing FLASH
Debug and and insure reliability of circuit

4. Our Method (Design) Deciding what to measure Choosing a sensor
Pros and cons of the AD590 sensor

5. AD590 Sensor -55°C to +150°C temp range Linear with ±0.2°C over range
Voltage in with current out
Output current 1 µA/K
Tn = ( I / ( 1μA / K ) ) = °C

6. AD22103 Sensor 3.3V temp. sensor 28 mV/°C Voltage in with temp out
0°C to +100°C temp range
Linearity Better Than 0.5%
Has its own op-amp
Added a 1u F capacitor

7. MSP430F449PZ Controller

8. MSP430F449PZ Controller Voltage Range 1.8 V to 3.6 V
16-Bit RISC Architecture
12-Bit A/D Converter With Internal Reference
Serial Communication Interface (USART), Select Asynchronous UART or Synchronous SPI by Software:
Two USART; USART0, USART1
Brownout Detector
Supply Voltage Supervisor/Monitor With Programmable Level Detection
Serial Onboard ProgrammingIntegrated LCD Driver for Up to 160 Segments
60KB+256B Flash Memory, 2KB RAM
