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
