LPC2194 Allgemeine Beschreibung
General descriptionThe LPC2194 is based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation and embedded trace support, together with 256 kilobytes (kB) of embedded high speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size applications, the alternative 16-bit Thumb Mode reduces code by more than 30% with minimal performance penalty.FeaturesKey features■ 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.■ 16 kB on-chip Static RAM and 256 kB on-chip Flash Program Memory. 128-bit wide interface/accelerator enables high speed 60 MHz operation.■ In-System Programming (ISP) and In-Application Programming (IAP) via on-chip boot-loader software. Flash programming takes 1 ms per 512 byte line. Single sector or full chip erase takes 400 ms.■ EmbeddedICE-RT and Embedded Trace interfaces offer real-time debugging with on-chip RealMonitor software as well as high speed real-time tracing of instruction execution.■ Four interconnected CAN interfaces with advanced acceptance filters. Additional serial interfaces are two UARTs (16C550), Fast I2C (400 kbits/s) and two SPIs™.■ Four channel 10-bit A/D converter with conversion time as low as 2.44 µs.■ Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs), Real Time Clock and Watchdog.■ Vectored Interrupt Controller with configurable priorities and vector addresses.■ Up to forty-six 5 V tolerant general purpose I/O pins. Up to 9 edge or level sensitive external interrupt pins available.■ Operating temperature range from −40 °C to +105 °C.■ 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop.■ On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz.■ Two low power modes, Idle and Power-down.■ Processor wake-up from Power-down mode via external interrupt.■ Individual enable/disable of peripheral functions for power optimization.■ Dual power supply: ◆ CPU operating voltage range of 1.65 V to 1.95 V (1.8 V ±0.15 V). ◆ I/O power supply range of 3.0 V to 3.6 V (3.3 V ±10%) with 5 V tolerant I/Opads.
Hauptmerkmale
- Key features brought by LPC2194/01 devices
- Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original device. They also allow for a port pin to be read at any time regardless of its function.
- Dedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are 5 V tolerant when configured for digital I/O function(s).
- UART0/1 include fractional baud rate generator, auto-bauding capabilities and handshake flow-control fully implemented in hardware.
- Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.
- SPI programmable data length and master mode enhancement.
- Diversified Code Read Protection (CRP) enables different security levels to be implemented. This feature is available in LPC2194/00 devices as well.
- General purpose timers can operate as external event counters.
