Does anyone know what this 32 pin chip is? Marked "23257-B" I think it might be equvalent to an ST72324 8bit MCU

I am trying to see if a chip marked "23257-B 1MU2114" is a predecessor to the ST72324 8 Bit MCU. It is used in an automotive application, and the documentation says the chip on the board should be an ST72324, but the "23257-B" is there instead (see picture). Does anyone know what the 23257-B is? Can't seem to find data sheet on it anywhere. Please advise - thanks - Dana
