The NXP microcontroller family LPC213x
uses a high-performance 32-bit ARM7
core that operates at up to 60 MHz.
Each device has up to 512 KB of on-chip
Flash and up to 32 KB of on-chip SRAM
memory.
In-System Programming (ISP) and In-
Application Programming (IAP) software
minimize programming time – each 256-
byte line takes only 1 ms to program,
and a single-sector or full-chip erase
takes only 400 ms.
A 128-bit-wide memory interface and
a patented memory accelerator enable
32-bit code execution from Flash with
zero wait-states. For applications where
code size is critical, an alternative 16-bit
Thumb mode reduces code by more
than 30% with minimal performance
penalties.
Each device is equipped with up to
two 10-bit A/D converters and a 10-bit
D/A converter. The A/D converters
have eight channels apiece and, on the
LPC213x/01 versions, result registers for
each channel.
Multiple serial communications
interfaces increase design flexibility,
provide larger buffer size, and deliver
higher processing power. There are two 16C550 UARTs, two
Fast I2C-bus (400 kbps) interfaces, and two SPI interfaces (one
with capabilities for buffering and variable data length).
LPC213x/01 UARTs feature a fractional baud-rate generator,
modem control, and auto-bauding.
There are two 32-bit timers (each with four capture and
compare channels), a PWM unit with six outputs, a real-time
clock, and a Watchdog timer.
For debugging, each device supports real-time emulation
and embedded trace support and has an integrated vectored
interrupt controller (VIC). Also, for compatibility with existing
tools, each device uses the standard ARM test/debug JTAG
interface.
The LPC213/01 versions have seven Fast I/O pins (5-V tolerant)
with switching up to 15 MHz. For all the devices, the operating
temperature range is -40 to 85 °C.
