3 / 30 page  3 FN8211.0 March 10, 2005 PIN ASSIGNMENTS TSSOP Pin CSP Pin Pin Name Pin Description 1A3 A0 Device Address Select Pin 0. This pin determines the LSB of the device address required to communicate using the 2-wire interface. The A0 pin has an on-chip pull- down resistor. 2B2 A1 Device Address Select Pin 1. This pin determines the intermediate bit of the device address required to communicate using the 2-wire interface. The A1 pin has an on-chip pull-down resistor. 3C2 A2 Device Address Select Pin 2. This pin determines the MSB of the device address re- quired to communicate using the 2-wire interface. The A2 pin has an on-chip pull-down resistor. 4B3 Vcc Supply Voltage. 5E3 WP Write Protect Control Pin. This pin is a CMOS compatible input. When LOW, Write Protection is enabled preventing any “Write” operation. When HIGH, various areas of the memory can be protected using the Block Lock bits BL1 and BL0. The WP pin has an on-chip pull-down resistor, which enables the Write Protection when this pin is left floating. 6C3 SCL Serial Clock. This is a TTL compatible input pin. This input is the 2-wire interface clock controlling data input and output at the SDA pin. 7D3 SDA Serial Data. This pin is the 2-wire interface data into or out of the device. It is TTL compatible when used as an input, and it is Open Drain when used as an output. This pin requires an external pull up resistor. 8E2 I1 Current Generator 1 Output. This pin sinks or sources current. The magnitude and di- rection of the current is fully programmable and adaptive. The resolution is 8 bits. 9E1 R1 Current Programming Resistor 1. A resistor between this pin and Vss can set the maximum output current available at pin I1. If no resistor is used, the maximum current must be selected using control register bits. 10 D1 R2 Current Programming Resistor 2. A resistor between this pin and Vss can set the maximum output current available at pin I2. If no resistor is used, the maximum current must be selected using control register bits. 11 C1, D2 Vss Ground. 12 B1 VSense Sensor Voltage Input. This voltage input may be used to drive the input of the on-chip A/D converter. 13 A1 VRef Reference Voltage Input or Output. This pin can be configured as either an Input or an Output. As an Input, the voltage at this pin is provided by an external source. As an Output, the voltage at this pin is a buffered output voltage of the on-chip bandgap refer- ence circuit. In both cases, the voltage at this pin is the reference for the A/D converter and the two D/A converters. 14 A2 I2 Current Generator 2 Output. This pin sinks or sources current. The magnitude and di- rection of the current is fully programmable and adaptive. The resolution is 8 bits. X9530 |
