New low cost ARM9 microcontroller with AES Decryption Engine and OTP memory

NXP Semiconductors has added two new microcontroller IC series named LPC314x and LPC315x to its ARM9-based microcontroller family called LPC31xx series. With the ARM926EJ processor core running faster at 270 MHz, the NXP LPC314x provide AES Decryption Engine and a secure One-Time-Programmable (OTP) memory. The LPC315x devices running at 180MHz include a Stereo Audio CODEC, Power Supply Unit and a Battery Charger.

The different parts available under LPC314x series are LPC3141 and LPC3143. The LPC3141 has One-Time-Programmable (OTP) memory for storing secure keys/USB product ID and the option to access JTAG securely. The LPC3143 is added with 128-bit AES Decryption Engine to the LPC3141 providing a mechanism to boot securely from NAND Flash, SPI-Flash, SD/MMC, eMMC/eSD and Managed NAND devices.

The two parts available under LPC315x are LPC3152 and LPC3154. The LPC3152 adds a Stereo Audio CODEC with Class AB Headphone Amplifier, Power Supply Unit (PSU) and Li-Ion charger to the LPC3141 feature set.

The LPC3154 adds a 128-bit AES Decryption Engine to the LPC3152 providing a mechanism to boot securely from NAND Flash, SPI-Flash, SD/MMC, eMMC/eSD and Managed NAND devices.

"This extension to our industry's lowest-cost LPC313x high-speed USB 2.0 OTG devices gives our customers a range of solutions for application-specific designs with higher performance and longer battery life," said Geoff Lees, vice president and general manager, microcontroller product line, NXP Semiconductors. "As always, we are committed to offering our customers the broadest ARM MCU offering in the industry and further cementing our position as an ARM leader."
