2.11
Flexible static memory controller (FSMC)
SPEAr300 provides a Flexible Static Memory Controller (FSMC) which interfaces the AHB
bus to external NAND/NOR Flash memories and to asynchronous SRAM memories.
Main features:
●
Provides an interface between AHB system bus and external parallel memory devices
●
Interfaces static memory-mapped devices including RAM, ROM and synchronous burst
Flash.
●
For SRAM and Flash 8/16-bit wide, external memory and data paths are provided
●
FSMC performs only one access at a time and only one external device is accessed.
●
Supports little-endian and big-endian memory architectures
●
AHB burst transfer handling to reduce access time to external devices
●
Supplies an independent configuration for each memory bank
●
Programmable timings to support a wide range of devices
–
Programmable wait states (up to 31)
–
Programmable bus turnaround cycles (up to 15)
–
Programmable output enable and write enable delays (up to 15)
●
Provides independent chip select control for each memory bank
●
Shares the address bus and the data bus with all the external peripherals. Only the chip
selects are unique for each peripheral
●
External asynchronous wait control
2.12
UART
Main features:
●
Hardware/software flow control
●
Modem control signals
●
Separate 16 x 8 (16 locations deep x 8-bit wide) transmit and 16 x 12 receive FIFOs to
reduce CPU interrupts
●
Speed up to 3 Mbps.

Fast IrDA controller (FIrDA)
The fast IrDA controller is a programmable infrared controller that acts as an interface to an
off-chip infrared transceiver. This controller is able to perform the modulation and the
demodulation of the infrared signals and the wrapping of the IrDA link access protocol
(IrLAP) frames.
