10 Introduction to the PanelView Plus CE Terminal
CPU
The system processor is an Intel mlCP 650MHz, ultra low-voltage
Celeron processor (P/N RJ80530VY650256) with 100 MHz front side
bus. There is 32k (16k instruction and 16k write-back data) of L1
cache memory and 256k of L2 cache memory integrated on the
Celeron processor. The thermal design allows for a maximum ambient
temperature of 55C without the use of a fan.
The primary support chipset is the 82810E Graphics And Memory
Controller Hub (GMCH) commonly referred to as the Eight-Ten-E. The
GMCH provides the interfaces between the CPU, system memory,
graphics displays, and downstream system I/O logic, including the
PCI bus. It integrates a system bus controller, 2D/3D graphics
accelerator, SDRAM controller, and an interface to a 82801BA I/O
Controller Hub (ICH2).
Memory Devices
There are three types of memory devices: Compact Flash ROM,
BootROM, and DRAM.
Compact Flash ROM
The logic board has two Type 2 Compact Flash connectors, one
internal and one external.
The internal connector is on the primary IDE interface and supports
the power requirements defined by the CompactFlash+ specification.
The internal CF “slot” is not hot-pluggable and supports only 3.3V CF
devices. The internal CF slot is populated at the factory and is
organized into 3 partitions as follows:
1. The compressed image of the Win CE operating system.
2. The compressed image of the persistent Win CE registry.
3. The FAT file system, presented as the volume named “\Storage
Card”
Only the fat file system is directly accessible to an application program
via standard Win32 file operations; e.g ReadFile().
