S3C2412 SAMSUNG 三星ARM微处理器

S3C2412 General Description The Samsung S3C2412 is optimized for embedded and mobile applications, featuring a 16/32-bit ARM926EJ-S core, on-chip peripherals that include a camera interface and low voltage supported by Samsung's low-power technology. This mobile processor gives designers of products such as portable GPS navigation devices, PDAs, and handheld POS a solution for reducing system cost while providing maximum flexibility.
In terms of flexibility, the S3C2412 has an enhanced NAND controller that enables both small-and large-block transfers as well as 4-bit ECC support to interface with an array of NAND flash such as MLC and SLC. The Samsung processor supports a variety of memory types such as NOR, SRAM and low-power mobile SDRAM as well as removable storage like SD and MMC. The S3C2412 also supports and enhanced set of power modes to reduce power consumption.
Displays are supported that range from 65K-color STN to 16M-color TFT-LCD in a variety of resolution, thus enhancing design flexibility. Samsung created the S3C2412 to power price-sensitive devices while still enabling broad features and performance. S3C2412 Block Diagram S3C2412 Features
