        I sent you a PM about this date sheet request

        I created an account to see if could find the data sheet as you can see from the terms and conditions it is not going to be available

        TS1102A is a micro controller from Renesas Technology Corp Japan

        And from I can see I do not think that this company put there data sheet available on the internet

        Unfortunately I have run into this issue with other company’s products that are made for a vendor that are not available no matter what you do to try to get it

        The chip is available from AliExpress and a couple of other vendors but no data sheet

          Renesas is notorious with this issue.

            i know there isnt a datasheet but is it possible to read a good one and program a new one ?
            the old one is dead but have access to a good working one .

              That’s a very good question on how you would program it.

                Well I think it would depend on whether or not you can reverse engineer the device circuit but with out data sheet I do not know if can figure out the micro controller data pins or not this to me would be the biggest problem

                  From the Chinese forum:
                  (Excerpt)

                  Lithium Battery Protection Board (TS1102A+N0412)

                  Circuit classification: Instruments Circuit name: Lithium battery protection board (TS1102A+N0412) Product description:

                  This circuit is based on the Renesas TS1102A microcontroller and controls the charging and discharging of the battery through the N0412. Avoid abnormal battery condition such as overcharging, overdischarging, overcurrent, short circuit, etc.

                  Main characteristics

                  TS1102A has

                  16 KB flash, 2 KB RAM

                  3 port port

                  Uart 16X16 --> 32bit, 16X16+32 --> 32bit, 32/32 --> 32bit

                  Operating voltage 1.6 ~ 5.5V, built-in high-speed generator, full temperature accuracy ±1%

                  ultra-low power consumption Timer stop interval wake up average power consumption less than 1uA
