EP7209-CB-D

The EP7209-CB-D is designed as a complete integrated system on a chip for enabling personal digital audio solutions. It is designed specifically for implementing audio processing algorithms in power sensitive applications.

EP7209-CB-D has many features. (1)Audio decoder system-on-chip allows for support of multiple audio decompression algorithms. (2)Ultra low power consumption for MP3 playback 87mW (typical) for 44.1 kHz samples/sec, 128 kbits/second. (3)ARM720T processor. (4)Dynamically programmable clock speeds of 18, 36, 49, and 74MHz at 2.5V. (5)Performance matching 100MHz intel pentium-based PC. (6)OEM customization integrated ARM720T RISC processor. (7)LCD controller interfaces directly to a single-scan panel monochrome LCD. (8)Memory controller decodes up to 6 separate memory segments of up to 256Mbytes each. (9)38,400 bytes (0x9600) of on-chip SRAM for fast program execution and/or as a frame buffer. (10)On-chip boot ROM for manufacturing support. Those are all the main features.

Some absolute maximum ratings of EP7209-CB-D have been concluded into several points as follow. (1)Its DC core, PLL and RTC supply voltage would be 2.9V. (2)Its DC I/O supply voltage pad ring would be 3.6V. (3)Its DC pad input current would be +/-10mA/pin; +/-100mA cumulative. (4)Its storage temperature no power would be from -40°C to 125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of EP7209-CB-D are concluded as follow. (1)Its CMOS input high voltage would be min 1.7V and max Vdd+0.3V. (2)Its CMOS input low voltage would be min -0.3V and max 0.8V. (3)Its schmitt trigger positive going threshold would be typ 1.6V and max 2.0V. (4)Its schmitt trigger negative going threshold would be min 0.8V and typ 1.2V. (5)Its schmitt trigger hysteresis would be min 0.1V and max 0.4V. And so on.
