Part number:7210-TQFP-R
IEEE 488.2 Controller Chip-44 Pin TQFP RoHS Compliant.

Since July 2019 is now being offered in the LQFP package. The LQFP package has a maximum seated height of 1.60 mm. For reference, the former TQFP packaging had a minimum seated height of 1.40 mm

The 7210-TQFP-R is a 44-pin DIP drop-in replacement part for the NEC µPD7210. The 7210-TQFP-R is 100% register-compatible and pincompatible with the NEC µPD7210 on power up. The 7210- TQFP-R performs all of the interface functions defined by the ANSI/IEEE Standard 488.1-1987, and it meets the additional requirements and recommendations of ANSI/IEEE Standard 488.2-1987. The 7210-TQFP-R performs complete IEEE 488 talker, listener, and controller functions.

On power up, the 7210-TQFP-R contains the complete register set of the NEC µPD7210, but can perform complete IEEE 488.2 controller functions through software. If you are an instrument developer, you can take advantage of IEEE 488.2 with minimal software modifications, yet keep the 44-pin hardware configuration. The default clock input is 8 MHz, but increased performance is available from the 7210- TQFP-R through software-selectable input values up to 20 MHz.

If you are an IEEE 488 instrument manufacturer looking for alternatives to existing NEC µPD7210 chip suppliers or planning to upgrade your designs to IEEE 488.2 without hardware changes, consider using the 7210-TQFP-R. Because the 7210-TQFP-R accepts faster clock inputs, performance increases without many firmware changes.
