LPC2105FBD48/01,15 Datasheet LPC2106FBD48/01,15, LPC2106FHN48/01,55, LPC2104FBD48/01,15 | P1-P3

1. General description

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

embedded trace support, together with 128 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.

Due to their tiny size and low power consumption, these microcontrollers are ideal for

applications where miniaturization is a key requirement, such as access control and

point-of-sale. With a wide range of serial communications interfaces and on-chip SRAM

options up to 64 kB, they are very well suited for communication gateways and protocol

converters, soft modems, voice recognition and low end imaging, providing both large

buffer size and high processing power. Various 32-bit timers, PWM channels, and 32

GPIO lines make these microcontrollers particularly suitable for industrial control and

medical systems.

Remark: Throughout the data sheet, the term LPC2104/2105/2106 will apply to devices

with and without /00 and /01 sufﬁxes. Sufﬁxes will be used to differentiate devices

whenever they include new features.

2. Features

2.1 New features implemented in LPC2104/2105/2106/01 devices

n Fast GPIO port enables port pin toggling up to 3.5 times faster than the original device

and also allows for a port pin to be read at any time regardless of its function.

n UART 0/1 include fractional baud rate generator, autobauding capabilities, and

handshake ﬂow-control fully implemented in hardware.

n Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.

n SPI programmable data length and master mode enhancement.

n Diversiﬁed Code Read Protection (CRP) enables different security levels to be

implemented.

n General purpose timers can operate as external event counters.

2.2 Key common features

n 16/32-bit ARM7TDMI-S processor.

n 16/32/64 kB on-chip static RAM.

n 128 kB on-chip ﬂash program memory. 128-bit-wide interface/accelerator enables high

speed 60 MHz operation.

LPC2104/2105/2106

Single-chip 32-bit microcontrollers

n 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.

n Vectored Interrupt Controller with conﬁgurable priorities and vector addresses.

n EmbeddedICE-RT interface enables breakpoints and watch points. Interrupt service

routines can continue to execute whilst the foreground task is debugged with the

on-chip RealMonitor software.

n Embedded Trace Macrocell enables non-intrusive high speed real-time tracing of

instruction execution.

n Multiple serial interfaces including two UARTs (16C550), Fast I

C-bus (400 kbit/s), and

SPI.

n Two 32-bit timers (7 capture/compare channels), PWM unit (6 outputs), Real Time

Clock and Watchdog.

n Up to thirty-two 5 V tolerant general purpose I/O pins in a tiny LQFP48 (7 mm × 7 mm)

package.

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

Loop with settling time of 100 µs.

n The on-chip crystal oscillator should have an operating range of 1 MHz to 25 MHz.

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

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

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

n Dual power supply:

u CPU operating voltage range of 1.65 V to 1.95 V (1.8 V ± 8.3 %).

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