LPC47N237 Szczegóły Produktu

General Description

The LPC47N237 is a 3.3V (5V Tolerant) PC99a/PC2001 compliant Docking I/O controller. The device, which implements the LPC interface, includes I/O functionality. LPC47N237’s LPC interface supports LPC I/O and DMA cycles. There is also a SMBus hosted GPIO Block.

The LPC47N237 provides 4 LPC general purpose pins which offer flexibility to the system designer. The legacy I/O included in the LPC47N237 are: a 16C550A compatible UART; one Multi-Mode parallel port including ChiProtect circuitry plus EPP and ECP. The parallel port is compatible with IBM PC/AT architecture, as well as IEEE 1284 EPP and ECP. The LPC47N237 incorporates sophisticated power control circuitry (PCC) which includes support for PME. The PCC supports multiple low power-down modes. The LPC47N237 is ACPI 1.0b/2.0 compatible.
