For engineers reviewing the LPC2134FBD64/01EL datasheet, LPC2134FBD64/01EL pinout, LPC2134FBD64/01EL application, or LPC2134FBD64/01EL equivalent, this page delivers verified functional partitioning, validated peripheral timing constraints, confirmed ADC/DAC resolution and conversion rates, and exact pin-level I/O tolerance and slew-rate specifications per NXP Rev. 5.1 datasheet.
Technical Context
The LPC2134FBD64/01EL implements an ARM7TDMI-S core with Thumb instruction set support, enabling 32-bit performance at 60 MHz while reducing code size by >30% in memory-constrained embedded applications. Its dual 8-channel 10-bit ADCs operate with 2.44 µs per channel conversion time and dedicated result registers to minimize interrupt latency.
Hardware-accelerated serial interfaces include two UARTs with fractional baud rate generators and auto-bauding, dual Fast I²C-bus (400 kbit/s), SPI/SSP with variable data length, and vectored interrupt controller with configurable priorities - all mapped to 47 5 V-tolerant GPIO pins in a 10 × 10 × 1.4 mm LQFP64 package.

The LPC2134FBD64/01EL achieves a maximum CPU clock frequency of 60 MHz using its on-chip programmable PLL, which settles in 100 µs. This frequency is sustained via a 128-bit wide memory interface and accelerator architecture that enables full-speed 32-bit code execution without wait states under typical conditions.
Does the LPC2134FBD64/01EL support in-system programming (ISP)?
Yes, the LPC2134FBD64/01EL supports In-System Programming via its on-chip bootloader, allowing flash memory to be erased and reprogrammed through UART0 without removing the device from the target board. Sector erase takes 400 ms and 256-byte programming completes in 1 ms.
How many analog-to-digital converter channels does the LPC2134FBD64/01EL provide?
The LPC2134FBD64/01EL integrates two independent 10-bit ADCs: ADC0 with eight channels (AD0.0–AD0.7) and ADC1 with eight channels (AD1.0–AD1.7), delivering up to 16 total analog inputs. Conversion time is as low as 2.44 µs per channel, and dedicated result registers reduce interrupt overhead.
What package type is used for the LPC2134FBD64/01EL?
The LPC2134FBD64/01EL is housed in a plastic low profile quad flat package (LQFP64), designated SOT314-2, with 64 leads and physical dimensions of 10 × 10 × 1.4 mm. It is pin-compatible with other LPC213x/01 variants in the same package family.
Can the LPC2134FBD64/01EL generate analog output signals?
Yes, the LPC2134FBD64/01EL includes a single 10-bit voltage-output DAC (AOUT), accessible on pin P0.25. This DAC supports programmable update rates and is commonly used for calibration references, audio tone generation, or analog biasing in sensor interfaces.
