1. General description

The LPC2194 is based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and

embedded trace support, together with 256 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.

With its compact 64-pin package, low power consumption, various 32-bit timers,

4-channel 10-bit ADC, four advanced CAN channels, PWM channels and 46 fast GPIO

lines with up to nine external interrupt pins this microcontroller is particularly suitable for

automotive applications such as a CAN gateway that connects several CAN busses or a

CAN bridge between sub networks at different speeds. Sensors with CAN interface or

debugging via CAN are additional applications that need more than two CAN interfaces. It

is also an adequate solution for industrial control, medical systems and fault-tolerant

maintenance buses. With a wide range of additional serial communications interfaces, it is

also suited for communication gateways and protocol converters as well as many other

general-purpose applications.

Remark: Throughout the data sheet, the term LPC2194 will apply to devices with and

without the /00 or /01 suffixes. The /00 or the /01 suffix will be used to differentiate from

other devices only when necessary.

2. Features and benefits

2.1 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.

LPC2194 NXP Semiconductors Single-chip 16/32-bit microcontroller Vectored IRQs have the middle priority. Sixteen of the interrupt requests can be assigned to this category. Any of the interrupt requests can be assigned to any of the 16 vectored IRQ slots, among which slot 0 has the highest priority and slot 15 has the lowest. Non-vectored IRQs have the lowest priority. The VIC combines the requests from all the vectored and non-vectored IRQs to produce the IRQ signal to the ARM processor.

Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed following a chip Reset and may be enabled by software. The program must configure and activate the PLL, wait for the PLL to Lock, then connect to the PLL as a clock source. The PLL settling time is 100 s. 6.18.
