LPC2194HBD64/01,15

The LPC2194HBD64/01,15 is a 16-/32-bit Microcontroller based on ARM7TDMI-S CPU with real-time emulation and embedded trace support. A 128-bit wide memory interface and an 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. The device incorporates 256kB embedded high speed flash, 16kB on-chip SRAM, 16-channel 10-bit A/D converter, 10-bit D/A converter, three 32-bit timers, four advanced CAN channels, PWM channels and 46 general-purpose I/O pins.

• In-system programming (ISP) and In-application programming (IAP)
• EmbeddedICE RT and embedded trace interfaces
• Four interconnected CAN interfaces with advanced acceptance filters
• Serial interfaces are two UARTs (16C550), Fast I2C-bus (400 Kbit/s) and two SPIs
• Two 32-bit Timers/external event counters, PWM unit and watchdog
• Vectored interrupt controller with configurable priorities and vector addresses
• Up to forty-six 5V tolerant GPIO, up to 9 edge or level sensitive external interrupt pins available
• 60MHz Maximum CPU clock available from programmable on-chip PLL
• On-chip crystal oscillator with an operating range of 1MHz to 30MHz
• 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
• Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original device
• Dedicated result registers for ADC(s) reduce interrupt overhead
• The ADC pads are 5V tolerant when configured for digital I/O function
• UART0/1 include fractional baud rate generator, auto-bauding capabilities and handshake flow-control
• 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)
• General purpose timers can operate as external event counters
