• Manufacturer Part Number: h8s-2628
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

This LSI has two independent serial communication interface (SCI) channels. The SCI can handle
both asynchronous and clocked synchronous serial communication. Serial data communication
can be carried out using standard asynchronous communication chips such as a Universal
Asynchronous Receiver/Transmitter (UART) or an Asynchronous Communication Interface
Adapter (ACIA). A function is also provided for serial communication between processors
(multiprocessor communication function). The SCI also supports an IC card (Smart Card)
interface conforming to ISO/IEC 7816-3 (Identification Card) as a serial communication interface
extension function.
Figure 14.1 shows a block diagram of the SCI.
14.1
Asynchronous mode
SCI0027A_0100020020900
Choice of asynchronous or clocked synchronous serial communication mode
Full-duplex communication capability
The transmitter and receiver are mutually independent, enabling transmission and reception to
be executed simultaneously.
Double-buffering is used in both the transmitter and the receiver, enabling continuous
transmission and continuous reception of serial data.
On-chip baud rate generator allows any bit rate to be selected
External clock can be selected as a transfer clock source (except for in Smart Card interface
mode).
Choice of LSB-first or MSB-first transfer (except in the case of asynchronous mode 7-bit data)
Four interrupt sources
Transmit-end, transmit-data-empty, receive-data-full, and receive error
requests.
The transmit-data-empty interrupt and receive-data-full interrupt can be used to activate the
data transfer controller (DTC).
Module stop mode can be set
Data length: 8 or 7 bits
Stop bit length: 2 or 1 bits
Parity: Even, odd, or none
Receive error detection: Parity, overrun, and framing errors
