SSM1105V Datasheet, PDF (1/4 Pages) STMicroelectronics – Scalar System Memory SSM for Image Processor ICs

FEATURES SUMMARY
s System solution for use with image processing
scalar ICs
– For LCD monitors, projectors, and TVs
– Compatible with Pixelworks PW11x/PWx64
families (and similar image processors or mi-
cro-controllers)
s Single integrated package, including:
– Dual bank Flash memories
– DDC, I²C, and PWM channels
– General purpose I/O
– Programmable logic
– In-System Programming via JTAG
s Dual bank Flash memories
– Provide concurrent operation
– 5 Mbit main Flash memory
– 384 Kbit secondary Flash memory (divided
into 10 small sectors)
– Programmable Decode PLD for flexible ad-
dress mapping of both memories
s Dual Display Data Channels (DDC)
– Supports DDC for both analog RGB and digi-
tal DVI video input channels
– DDC1/DDC2B VESA standard compliant
– 256 byte SRAM buffer for each DDC channel
s Dual independent I²C channels
– Each capable of master or slave operation
– Control A/D converters, video decoders, and
future devices (tuner, audio, etc.)
s Four Pulse Width Modulator (PWM) channels
– 16-bit resolution for period and for duty cycle
– 16-bit clock prescalers
s Seven I/O ports with 52 I/O pins for Multifunction
I/O: GPIO, DDC, I²C, PWM, PLD I/O, and JTAG
s 3000 gate PLD with 16 macrocells, for creating
glue logic, state machines, clock dividers,
