Individual direction control for the port data lines
Four peripheral control lines for functions such as handshaking
40-pin through-hole dual inline package

For Atari 400 and 800 boards that specify a 6520 PIA. Atari service documentation identifies the 6520 PIA as CO14795. Check the original chip marking and board documentation for the required pinout and timing before installation.
Q&A:
Q: Can I use this in an Atari 400 or 800?
A: It is suitable for Atari 400 and 800 boards that specify a 6520 PIA and match the chipβs pinout and timing.
Q: Does the listing include two chips?
A: It includes one chip with both SY6520 and SY6820 printed on the package.
Troubleshooting:
If an I/O port does not respond, check the 5 V DC supply, chip-select signals, and register selection against the service manual and Synertek datasheet. Verify that the data direction register is set for the intended operation.
