Rev. 1.0 — 22 September 2021

Product data sheet

1 General description

SC18IM704 is designed to serve as an interface between the standard UART port of a

protocol, arbitration and timing. The host communicates with SC18IM704 with ASCII

messages protocol; this makes the control sequences from the host to SC18IM704

become very simple.

SC18IM704 is a functional replacement for SC18IM700 with exception of:

• New pinout

• GPIO no longer has quasi bidirectional mode

• Lower operating supply voltage level (1.71 V vs 2.4 V)

• Temperature range of -40 to +105 °C vs -40 to +85 °C

• Device is rotated 180 degrees in the tape pocket; pin 1 is now in Quadrant 1
