NXPs' ARM7 with Hi-Speed USB and 1MB of Flash - LPC2888 and LPC2880

Page Contents:   [ Evaluation Board | Featured Products | Datasheets | Application Notes | Buy Now ]

The LPC2800 family of microcontrollers is based on an ARM7TDMI-S™ CPU with real-time emulation. Multiple serial communication interfaces, including Hi-Speed USB (480 Mbps), increase design flexibility, provide larger buffer size and deliver high processing power.

The LPC2880 has 64 KB of on-chip RAM, 32 KB of on-chip ROM, an external memory controller for use with SDRAM, SRAM, and NOR and NAND Flash, plus an 8KB cache for enhanced performance from external memory. The LPC2888 builds on the LPC2880 architecture by adding 1 MB of on-chip Flash memory. The LPC2800 architecture includes high efficiency switching and linear regulators in power supply subsystems that it supports.
