Description

SC73P1601MA is a programmable remote transmitter (4-bit MCU) with an infrared transmitting transistor and built-in 2K OTP program memory. It supports in-system program (ISP) which optimizes stock control. Due to the embedded infrared transmitting transistor, the need for peripheral components is reduced, leading to cost reduction. Additionally, SC73P1601MA supports a quick mask function that allows for faster mass production delivery compared to traditional masks cycles. It is available in several packages and is pin-to-pin compatible with all products in the SC73C16 and SC73P16 series.
