The array consists of 102 pixels: 100 inner pixels and 2 end pixels. The inner pixels measure 85 μm (H) by 77 μm (W) on 85-μm centers and the end pixels are 132 μm (H) by 49 μm (W). Associated with each pixel is a charge integrator/amplifier and sample-hold circuit. All pixels have concurrent integration periods and sampling times. The array is split into three 34-pixel zones, with each zone having programmable gain and offset levels. Data communication is accomplished through a three-wire serial interface. Intended for use in high performance, cost-sensitive scanner applications, the TSL3301CL is based on a linear sensor array die that has expanded capability, including multi-die addressing and cascade options. Please contact TAOS for additional information on die and multi-die package availability.

These commands cause the device to perform functions such as reset, integrate, sample, etc. Table 3 summarizes the command types and formats and Table 4 lists the command set for the TSL3301CL. Each command is described in more detail below. Table 3. Command Type and Format Summary COMMAND TYPE Action command Register write < Command byte > < Command byte > < Data byte > FORMAT Table 4.
