Holtek on the electronic chip issues

Good morning ladies and gentlemen, I would like to ask everyone holtek ht46r23 a814s0887 What is the specific electronic chips, where you can buy, I mean, where Beijing has sold it?!

summary

HT46R23/HT46C23 is a high-performance 8-bit RISC single-chip, the need for A / D converter products are designed, such as sensor inputs.HT46C23 version of the mask with the OTP version HT46R23 pin and function exactly the same.

Low-power, I / O flexibility, programmable divider , Counters, select the type of oscillation, multi-channel A / D conversion, and pulse measurement function, I2C communications, and the suspension of wake-up function, so that this single chip can be widely used in the sensor A / D conversion, motor control, industrial control, consumer Products such as system.
