NXP ARM9 MCU family to add two new devices

NXP Semiconductors (NXP Semiconductors, the independent semiconductor company founded by Philips) today announced that, LPC31xx series pushed LPC314x and MTV312MV64 datasheet and LPC315x two new devices further enriched currently ARM9-based portfolio. LPC314x NXP ARM926EJ processor core based on high performance devices, on the basis of the LPC313x device provides several new features, including AES decryption engine and MTV312MV64 price and the safety of one-time programmable (OTP) memory. LPC314x the operating frequency is 270MHz, runs faster than a 50% increase LPC313x devices. LPC315x the operating frequency is 180MHz, and MTV312MV64 suppliers and further increase the stereo audio codecs, power supply units and battery chargers.

LPC31xx family of integrated high-speed (480 Mbps) USB 2.0 OTG and advanced power management features, embedded designers can use their high-performance, low cost, energy-efficient and smaller code size advantages for consumer, industrial, medical, communications and automotive infotainment systems market.

LPC314x

LPC314x include two components: LPC3141 and LPC3143. LPC3141 provides a unique ID is not only equipped with the safety of one-time programmable (OTP) memory and can store the security key / USB Product ID and security access for users JTAG election items. LPC3143 LPC3141 based on an increase in the 128-bit AES decryption of the engine, providing a mechanism for NAND flash memory from, SPI flash memory, SD / MMC, eMMC / eSD and managed NAND such as safety equipment to start.

90nm process design from the LPC314x device equipped with a 270 MHz ARM926EJ core, but also with a 16-KB data within the cache ,16-KB instruction cache, and 192KB on-chip SRAM. LPC314x with 8 / 16 bit SRAM and SDRAM external bus interface and can support SDHC, MMC / SDIO and CE-ATA peripherals, memory card interface. Serial interfaces include SPI / SSI, I2C, I2S, UART, PWM and PCM (pulse code modulation) interface. On the basis of these features include 10-bit A / D, general purpose timers, watchdog timer, and multiple GPIO. LPC314x also integrates 4/8/16 bit 6800/8080 compatible LCD interface, interactive visualization capabilities to meet the application requirements.

LPC315x

LPC315x include two components: LPC3152 and LPC3154. LPC3152 LPC3141 combination of features in an increase on the basis of Class AB headphone amplifier with stereo audio codecs, power supply unit, and lithium battery charger. Use of the product, designers can achieve the best energy-saving effect, while in no way affect the performance or increase in cost. Power unit allows the system to the battery voltage or USB direct power supply to run directly to the supply voltage to the best the rest of the drive system. With its built-in battery charger, using USB connection or AC power adapter to charge the lithium battery. The charger can also monitor battery voltage, charge current and battery and the chip temperature. Flexible clock generation unit (CGU) provides dynamic clock gating and adjustment, and thus further optimize the systems low energy consumption.

LPC3154 LPC3152 based on an increase in the 128-bit AES decryption engine has to provide a NAND flash memory from, SPI flash memory, SD / MMC, eMMC / eSD and start the Managed NAND devices such as security mechanism.

NXP Semiconductor vice president and general manager, microcontroller product line, said Geoff Lees: "This time the expansion of the industrys lowest cost high-speed USB 2.0 OTG device LPC313x our customers a variety of application-specific solutions, not only better performance, and longer battery life. We are always trying to provide the industrys most complete category ARM MCU products, while also further strengthen our ARM-based products in the field of leadership. "
