LPC2194

Single-chip 16/32-bit microcontroller

2.2 Key features common for all devices

I 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.

I 16 kB on-chip SRAM and 256 kB on-chip ﬂash program memory. 128-bit wide

interface/accelerator enables high speed 60 MHz operation.

I In-System Programming (ISP) and In-Application Programming (IAP) via on-chip

bootloader software. Flash programming takes 1 ms per 512 B line. Single sector or

full chip erase takes 400 ms.

I 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.

I Four interconnected CAN interfaces with advanced acceptance ﬁlters. Additional serial

interfaces are two UARTs (16C550), Fast I2C-bus (400 kbit/s) and two SPIs.

I Four channel 10-bit ADC with conversion time as low as 2.44 µs.

I Two 32-bit timers (with four capture and four compare channels), PWM unit (six

outputs), Real-Time Clock and Watchdog.

I Vectored Interrupt Controller with conﬁgurable priorities and vector addresses.

I Up to forty-six 5 V tolerant general purpose I/O pins. Up to nine edge or level sensitive

external interrupt pins available.

I Operating temperature range from −40 °C to +125 °C.

I 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked

Loop with settling time of 100

µs.

I On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz.

I Two low power modes, Idle and Power-down.

I Processor wake-up from Power-down mode via external interrupt.

I Individual enable/disable of peripheral functions for power optimization.

I Dual power supply:

N CPU operating voltage range of 1.65 V to 1.95 V (1.8 V ± 0.15 V).

N I/O power supply range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5 V tolerant I/O pads.
