SAA5500PS

The SAA5500PS is designed as one kind of standard TV microcontroller device that can offers a range of functionality from non-text, 16-kbyte program ROM and 256-byte Random Access Memory (RAM). And SAA5500PS provides control functions for the television system, OSD, and some versions include an integrated data capture and display function.

Features of the SAA5500PS are:(1)Single-chip microcontroller with integrated on-screen display (OSD); (2)Versions available with integrated data capture; (3)One Time Programmable (OTP) memory for both program Read Only Memory (ROM) and character sets; (4)Single power supply: 3.0 to 3.6 V; (5)5 V tolerant digital inputs and I/O; (6)29 I/O lines via individual addressable controls; (7)Programmable I/O for push-pull, open-drain and quasi-bidirectional; (8)Two port lines with 8 mA sink (at <0.4 V) capability, for direct drive of Light Emitting Diode (LED); (9)Single crystal oscillator for microcontroller, OSD and data capture; (10)Power reduction modes: Idle and Power-down; (11)Byte level I2C-bus with dual port I/O; (12)Pin compatibility throughout family; (13)Operating temperature: -20 to +70 °C.

The absolute maximum ratings of the SAA5500PS can be summarized as:(1)supply voltage (all supplies): -0.5 to +4.0 V;(2)input voltage (any input): -0.5 to VDD+0.5 or 4.1 V;(3)output voltage (any output): -0.5 to VDD+0.5 V;(4)output current (each output): ±10 mA;(5)DC input or output diode current: ±20 mA;(6)operating ambient temperature: -20 to +70 °C;(7)storage temperature: -55 to +125 °C.
