General description
The LPC804 are an ARM Cortex-M0+ based, low-cost 32-bit MCU family operating at
CPU frequencies of up to 15 MHz. The LPC804 supports 32 KB of flash memory and
4 KB of SRAM.
The peripheral complement of the LPC804 includes a CRC engine, two I2C-bus
interfaces, up to two USARTs, one SPI interface, Capacitive Touch Interface (Cap Touch),
one multi-rate timer, self-wake-up timer, one general purpose 32-bit counter/timer, one
12-bit ADC, one 10-bit DAC, one analog comparator, function-configurable I/O ports
through a switch matrix, an input pattern match engine, Programmable Logic Unit (PLU),
and up to 30 general-purpose I/O pins.
For additional documentation related to the LPC804 parts, see Section 19.
Features and benefits
 System:
 ARM Cortex-M0+ processor (revision r0p1), running at frequencies of up to
15 MHz with single-cycle multiplier and fast single-cycle I/O port.
 ARM Cortex-M0+ built-in Nested Vectored Interrupt Controller (NVIC).
 System tick timer.
 AHB multilayer matrix.
 Serial Wire Debug (SWD) with four break points and two watch points. JTAG
boundary scan (BSDL) supported.
 Memory:
 Up to 32 KB on-chip flash programming memory.
 Code Read Protection (CRP).
 4 KB SRAM.
 Dual I/O power (LPC804M111JDH24):
 Independent supplies on each package side permitting level-shifting signals from
one off-chip voltage domain to another and/or interfacing directly to off-chip
peripherals operating at different supply levels.
 ROM API support:
 Boot loader.
 Supports Flash In-Application Programming (IAP).
 Supports In-System Programming (ISP) through USART.
 On-chip ROM APIs for integer divide.
