The memory controller SAA4952WP is the improved version of the SAA4951WP. The circuit has been designed for high-end TV sets using 2fH technics. For basic feature modules a 1fH mode can be activated. In this situation the controller supplies the system with a line-locked clock. The SAA4952WP has been designed to be able to operate in the hardware environment of the SAA4951WP.

The SAA4952WP provides all necessary write, read and clock pulses to control different field memory concepts. Furthermore the drive signals for the horizontal and vertical deflection power stages are also generated.

The SAA4952WP is connected to a microcontroller via an 8-bit data bus. The microcontroller receives commands via the I²C-bus. Due to this fact the START and STOP conditions of the main output control signals are programmable and the SAA4952WP can be set in different function modes depending on the TV feature concept that is used.
