Device Description
The X96012 combines two Programmable Current
Generators, and integrated EEPROM with Block Lock
protection in one package. The combination of the X96012
functionality and Intersil’s QFN package lowers system cost,
increases reliability, and reduces board space requirements.
Two on-chip Programmable Current Generators may be
independently programmed to either sink or source current.
The maximum current generated is determined by using an
externally connected programming resistor, or by selecting
one of three predefined values. Both current generators
have a maximum output of ±3.2mA, and may be controlled
to an absolute resolution of 0.39% (256 steps/8-bit).
Both current generators may be driven using an on-board
temperature sensor, an external sensor, or Control
Registers. The internal temperature sensor operates over a
very broad temperature range (-40
°C to +100°C). The
sensor output (internal or external) drives an 8-bit A/D
converter. The six MSBs of the ADC output select one of
64 bytes from each nonvolatile look-up table (LUT).
The contents of the selected LUT row (8-bit wide) drives the
input of an 8-bit D/A converter, which generates the output
current.
All control and set-up parameters of the X96012, including
the look-up tables, are programmable via the 2-wire serial
port.
The general purpose memory portion of the device is a
CMOS serial EEPROM array with Intersil’s Block Lock
protection.
The EEPROM array is internally organized as 272x8 bits
with 16-Byte pages, and utilizes Intersil’s proprietary Direct
Write cells, providing a minimum endurance of 100,000
Page Write cycles and a minimum data retention of 100
years.
