Intermec 073290-001 User Manual

The SRAM-based FPGA supports two programming models. 

In normal operation, the FPGA is downloaded at boot time and on every 
resume by the FPGA download driver running on the PXA255 processor. 
See “FPGA Download” on page 48 for details. 

For debug purposes (for instance, if the OS is not running), the FPGA can 
be also programmed via the JTAG port using the 073048 JTAG board 
described in “Field-Access Debug Port” on page 93. 

The flash-based firmware in the Power Supply Controller may be 
reprogrammed using proprietary programming tools from Microchip 
(ProMate II programmer with an AC004004 adapter module, and 
MPLAB development environment software). The programming signals 
are accessible through debug port P1 using the 073048 JTAG board 
described in “Field-Access Debug Port” on page 93. 

All of the docks/chargers use the same Texas Instrument L-ion charging 
chip (BQ2954). In regards to charging, the only difference between all of 
these accessories is the amount of charge current. 

The power supply lump (073573) is also common to all docks and 
chargers. The lump supplies up to 4.15A @ 12 VDC.
