FAQ
What is the maximum operating frequency of the LPC1114FHN33/203?
The LPC1114FHN33/203 operates at a maximum CPU frequency of 50 MHz, achieved using either the internal 12 MHz RC oscillator with PLL multiplication or an external crystal up to 25 MHz. This frequency enables deterministic real-time response for control loops and communication protocols without requiring high-frequency external clocks.
Does the LPC1114FHN33/203 support in-system programming (ISP)?
Yes, the LPC1114FHN33/203 supports In-System Programming (ISP) via its built-in bootloader, allowing firmware updates over UART without external programming hardware. This capability is enabled by the on-chip ROM-based ISP routine and requires only a standard UART connection and appropriate host software.
What is the ADC resolution and channel count on the LPC1114FHN33/203?
The LPC1114FHN33/203 integrates a 10-bit successive-approximation ADC with multiplexing across eight input channels (AD0–AD7). All eight channels are accessible in the HVQFN33 package, supporting simultaneous monitoring of multiple analog signals such as temperature, voltage, and current in compact embedded systems.
Is the LPC1114FHN33/203 pin-compatible with other LPC111x HVQFN33 variants?
Yes, the LPC1114FHN33/203 shares identical pinout and electrical characteristics with all other LPC111x devices in the HVQFN33 package (e.g., LPC1111FHN33/203, LPC1112FHN33/203), differing only in flash size, SRAM, and feature enablement (e.g., WWDT presence). This allows direct substitution within the same package family for design reuse.
What debug interface does the LPC1114FHN33/203 support?
The LPC1114FHN33/203 supports Serial Wire Debug (SWD) using two dedicated pins: SWCLK (pin 6) and SWDIO (pin 32). This 2-pin interface enables full debugging, flash programming, and real-time tracing through standard ARM-compliant tools such as LPC-Link2 and J-Link, without requiring JTAG header space.
