Introduction
The PNX1500 Media Processor Series is a complete Audio/Video/Graphics system
on a chip that contains a high-performance 32-bit VLIW processor, TriMedia
TM3260, capable of high quality software video (multi-video standard digital decoder/
encoder and image improvement), audio signal processing, as well as general
purpose control processing. It can either be used in standalone, or as an accelerator
to a general purpose processor. The PNX1500 processes the input signals by
utilizing several Audio/Video and co-processor modules before send them to the
external peripherals. These modules provide additional video and data processing
bandwidth without taking away precious CPU cycles. The combination of the CPU
and co-processor modules makes the PNX1500 System On-Chip (SoC) suitable for
most applications, especially those requiring high level of processing power/
throughput at a reduced cost.
PNX1500 derivatives available. Throughout this document PNX1500 or PNX15xx
Series will be used to refer to any of the derivatives of PNX1500 devices unless
otherwise specied.

Pin Description
2.1 Boundary Scan Notice
PNX1500 implements full IEEE1149.1 boundary scan. Any pin designated ‘IN’ only
(from functionality point of view) can function as an output during boundary scan.
2.2 I/O Circuit Summary
PNX1500 has a total of 275 functional pins, 1 reserved pin, and 180 power pins.
The regular I/Os are powered a 3.3 V power supply. The DDR-I interface supports
supports a 2.5 V to 2.6 V power supply depending on the PNX15xx Series device..
PNX1500 supports 5 V input tolerant pins for some specic interfaces such as PCI
and I2C.
