VSP1000

The VSP1000 is a high performance, low power identification system building block which supports several modes of operation. The device has an internal programmable memory array which can allow or up to 39 bits of internal identification data or about discrete codes. The device is capable of sending internal data in 21, 27, 33, and 39 bit formats. The device can also be programmed to send up to 18 bits of data from external data registers, and it can also be placed in a mode which allows an external intelligent device to take over control of the chip and send an unlimited amount of 7 bit data with automatic parity generation. The device has a wide voltage operating range and consumes little operating power, due to its pseudo-static architecture. The clock rate can be as low as DC and as high as 3.0 MHz. The data format includes word parity and frame checksum for high data integrity.

The features of VSP1000 can be summarized as (1)three major operating:1. Internal data - 21, 27, 33, or 39 bits of data; 2. Internal/external data:21 bits internal and 6, 12, or 18 bits of external data; 26 bits internal and 6 or 12 bits of external data; 33 bits internal and 6 bits of external data; 3. external streaming data - unlimited data of 7 bit words with automatic parity generation; (2)wide operating range 1.25 TO 7 VOLTS (VCC), DC TO 3.0 MHz CLOCK, DATA RATE OFF(clk)/16 ; (3)PC (or clone) programming card and software available; (4)Low power consumption of 0.5 uA/KHz (typ).

The absolute maximum ratings of VSP1000 are (1)supply voltage - vcc: 125(min)/500(typ)/700(max)volts ; (2)gnd:0/0/0volts ; (3)input voltage - high: vcc/2(min)/vcc+5(max) volts ; (4)low:-03(min)/vcc/6(max)volts ; (5)temperature - plastic: -40(min)/70(max) degc; (6)ceramic: -55(min)/85(max)degc.
