高性能和低功耗
Combined`with`large`accelerated`Flash`and`SRAM`memories`
and`a`set`of`unique`configurable`peripherals,`the`150`MHz`
LPC4300`enables`customers`to`develop`a`wide`range`of`
applications`such`as`motor`control , ` power`management , `
industrial`automation ,机器人` `医` automotive`
accessories`and`embedded`audio.`
结合MCU和DSP功能
The`Cortex-M4`processor`combines`the`benefits`of`a`
microcontroller` - `integrated`interrupt`control , ` low`power`
模式, ` low`cost`debug`and`ease`of`use` , `with`high-
performance`digital`signal`processing`features`such``
as`single - cycle`MAC , ` single`instruction`multiple`data` ( SIMD ) `
技术, saturating`arithmetic ` ` and`a`floating`point`unit.`
A`Cortex-M0`coprocessor`offloads`many`of`the`data`movement`
and`I / O`handling`duties`that`can`drain`the`bandwidth`of`the`
Cortex-M4`core.`This`allows`the`Cortex-M4`to`concentrate`fully`
on`crunching`numbers`for`digital`signal`control`applications 。
