IC Identification

I'm attempting to repair a PC board for a RadioShack PT Cruiser remote control car. The IC (20-pin) has the following numbers printed on the top: S111g, KJET IC001, OU97112.

In the tech manual, the IC is identified as KS57C0301.

(1) Program memory is 1K byte (KS57C0301) and 2K byte (KS57C0302).
(2) Data memory is 128x4 bit (KS57C0301) and 256x4 bit (KS57C0302).

Parts from RadioShack are no longer available. Any help in identifying a substitute would be appreciated.
