New LPC32x0 Devices

NXP introduces 4x new LPC3000 microcontrollers integrating key features for ARM9 with up to 256-KB SRAM, Ethernet, USB and LCD-Controller.

Built around a 90-nm, 208-MHz ARM926EJ-S CPU core and a Vector Floating Point (VFP) coprocessor, the NXP LPC32x0 family is designed for applications that require high performance, high integration, and low power consumption. The VFP coprocessor increases the speed of typical calculations by a factor of four to five in scalar mode, and much more in optimized vector mode. Advanced process technology optimizes each microcontroller’s intrinsic power, and software-controlled features provide best-in-class power management. Each LPC32x0 microcontroller has up to 256 KB of internal SRAM, and an external memory controller that supports DDR and SDR SDRAM, SRAM, Flash, and static devices. The external-memory controller can boot-up from NAND Flash, SPI memory, UART, or SRAM.

On the LPC3230 and the LPC3250, there is also a flexible LCD controller that supports STN and TFT panels, and offers a dedicated DMA controller and programmable display resolution up to 1024 x 768 and up to 16 M colors.
Multiple interfaces for serial communications increase design flexibility, provide larger buffer size, and deliver higher processing power. The LPC3240 and LPC3250 microcontrollers have a 10/100 Ethernet MAC with a dedicated DMA controller. Every LPC32x0 microcontroller also has a USB interface that supports device, host, and On-The-Go (OTG) operation. There are four standard 16C550 UARTs (one supports IrDA), three highspeed (up to 921,600 bps) UARTs, two Fast I²C-bus (400 Mbps) interfaces with slave, single, and multi-master support, two SPI/ SSP ports, and a function for automatic keyboard scanning that supports 8 x 8 keys. There are also two I²S interfaces, each with separate input and output channels. Each channel can be operated independently on three pins, or, with only four pins, the input and output of one I²S interface can be used.

Each LPC32x0 microcontroller has a 10-bit, 400-kHz A/D converter with three channels and a touchscreen interface, five 32-bit timers with capture/compare channels, a 32-bit timer driven by the real-time clock, eleven PWM channels, and a Watchdog timer. There is also a real-time clock with a separate clock and power domain, a dedicated 32-kHz oscillator, a Secure Digital (SD) interface, and an integrated interrupt controller that supports up to 73 interrupt sources. Data movement is managed by an eight-channel, generalpurpose DMA controller that can be used with SD ports, UARTs, I²S ports, SPI interfaces, or memory-to-memory transfers.
A seven-layer, 32-bit, 104-MHz AHB matrix provides a separate bus for each of the seven AHB masters (D-cache, I-cache, two DMA, Ethernet MAC, USB controller, and LCD controller). This eliminates arbitration delays, except when two masters attempt to access the same slave at the same time.
An on-chip PLL lets the CPU operate up to its maximum rate without a high-frequency crystal. A second PLL enables operation from the 32-kHz real-time clock instead of the external crystal.
The core voltage supports 1.2V, while the I/O ports support 1.8, 2.8, and 3.0V. The operating temperature range -40 to +85 °C.
In ultra-low power mode, the core operates down to 0.9V. For debugging, LPC32x0 microcontrollers use a JTAG interface with a 2K x 24-bit emulation trace buffer and supports real-time emulation.

With the large set of on-chip peripherals and the Vector Floating Point Co-processor, the LPC3000 architecture is very well suited for any high processing power application with LCD, connectivity and portability requirements.
