Z550 UART
0.5ตm Technology Mega Macrocell for Universal Asynchronous Receiver/Transmitter DESCRIPTION
The Z550 UART Mega Macrocell is a featured library element in all of OKI's 0.5ตm Sea of Gates and 0.5ตm Customer Structured Array families. The OKI implementation of the mega macrocell is fully compatible with industry standard 16550 functions.
The Z550 UART Mega Macrocell is an Asynchronous Communication Element (ACE), functionally equivalent to the industry standard 16550 with 16 byte FIFOs available on both the transmitter and receiver. It serves as a serial I/O interface in microcomputer systems performing serial to parallel conversions on data characters received from peripheral devices or modems and parallel to serial conversions on data characters transmitted by the CPU. In FIFO mode, the FIFOs are enabled allowing 16 bytes of data to be stored during both transmit and receive operations. The receive FIFO also provides three bits per byte of error data. The status of the ACE can be read at any time by the CPU. Available information includes the type and condition of transfer operations being performed and error conditions involving parity, overrun, framing or break interrupt. The ACE includes a built in baud rate generator with 18 programmable baud rates.
FEATURES
ท Full double buffering ท Full status reporting ท 16 byte receive and transmit FIFOs reduce CPU interrupts ท Independent control of transmit, receive, line status data set interrupts and FIFOs ท Modem control signals include: CTS, DCD, DSR, DTR, RI, RTS ท Programmable serial interface characteristics: Supported ASIC Families
Family Name MSM13R0000 MSM98R000
This Mega Macrocell Data Sheet contains all necessary information to enable the user to design a circuit using the Z550 functions for OKI's 0.5ตm Sea of Gates and 0.5ตm Customer Structured Array families.
Family Type Sea of Gates Customer Structured Array
- 5, 6, 7, or 8 bit characters - odd, even, or no parity generation and detection - 1, 1.5, or 2 stop bits
ท Programmable Baud Rate Generator (dc to 56k baud) ท Unique OKI methodology for input timing analysis ท Tailored design flow and test procedure alleviates user from test vector generation to verify Z550 functionality ท Specially developed software merges OKI test vectors with the user's circuit
