LPC315x - ARM9 MCU with HS USB 2.0 OTG and Security Engine

NXP LPC315x iconThe NXP LPC3154/2 family combines an 180 MHz ARM926EJ CPU core, High Speed USB 2.0 OTG, up to 192 KB SRAM, NAND Flash Controller with a 128-bit AES Decryption Engine (LPC3154), flexible external bus interface, three channel 10-bit A/D and a myriad of serial and parallel interfaces. To optimize system power consumption, the LPC3154/2 have multiple power domains and a very flexible Clock Generation Unit (CGU) that provides dynamic clock gating and scaling.

 

The integrated Power Supply Unit (PSU) allows the system to run directly from the battery or the USB power. The built-in charger allows a Li-Ion battery to be charged from the power supplied by a USB connection or by an AC adapter. The charger also monitors battery voltage, charge current, battery and chip temperature.

 

The integrated Stereo Audio CODEC with Class AB Headphone Amplifier is ideal for high-quality audio applications.

 

The secure One-Time-Programmable (OTP) memory provides a unique ID, the ability to store secure keys/USB product ID, and the option to access JTAG securely.
