Product details
Overview
LPC2109FBD64/01 from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP64 package, featuring 64 kB flash, 8 kB SRAM, one CAN channel, four-channel 10-bit ADC (2.44 µs conversion), and 46 GPIO pins with nine external interrupt inputs - deployed in automotive control units and industrial fault-tolerant maintenance buses.
For engineers reviewing the LPC2109FBD64/01 datasheet, LPC2109FBD64/01 pinout, LPC2109FBD64/01 application, or LPC2109FBD64/01 equivalent, key selection criteria include its single-CAN capability, /01-suffix Fast GPIO acceleration, 60 MHz CPU clock with PLL, 5 V-tolerant ADC pads in digital I/O mode, and support for ISP/IAP firmware updates without external programmer.
Technical Context
The LPC2109FBD64/01 implements an ARM7TDMI-S core with Thumb instruction set for code density optimization and real-time emulation via EmbeddedICE-RT. Its memory subsystem uses a 128-bit wide interface and accelerator to sustain 60 MHz operation from on-chip flash.
Peripheral integration includes two 32-bit timers (four capture/compare channels each), PWM unit with six outputs, RTC, watchdog, UART0/1 with fractional baud rate generators, Fast I²C (400 kbit/s), dual SPI interfaces (one shared as SSP), and a dedicated 10-bit ADC with burst mode and pin-triggered conversion - all mapped through a configurable Pin Connect Block.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM7TDMI-S 16/32-bit RISC processor with Thumb mode; enables 30 % smaller code size vs. ARM mode with minimal performance loss. |
| Max Clock Speed | 60 MHz via on-chip PLL (100 µs settling time); supports real-time deterministic execution in automotive timing-critical tasks. |
| Flash Memory | 64 kB ISP/IAP flash; allows field firmware updates and secure boot via Code Read Protection (CRP) levels. |
| SRAM | 8 kB on-chip SRAM; accessible as 8/16/32-bit; used for stack, heap, and critical variables in interrupt service routines. |
| ADC | Four-channel 10-bit successive approximation ADC; 2.44 µs conversion time; 0–3 V input range; dedicated result registers per channel reduce CPU overhead. |
| CAN Interface | One CAN 2.0B-compliant controller; supports up to 1 Mbit/s data rate; includes advanced acceptance filters for message filtering in vehicle networks. |
| I/O Capability | 46 total GPIO pins; 5 V tolerant when configured as digital I/O; nine external interrupt-capable pins (EINT0–EINT3 plus shared functions). |
| Power Supply | Dual-rail: 1.65–1.95 V (1.8 V ±0.15 V) for core; 3.0–3.6 V (3.3 V ±10 %) for I/O; enables mixed-voltage system interfacing. |
Pinout & Package
Package: LQFP64 (SOT314-2), plastic low-profile quad flat package, 10 × 10 × 1.4 mm body, lead pitch 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]/TXD0/PWM1 | UART0 transmit / PWM output | Primary serial debug interface; PWM1 usable for motor control or LED dimming without peripheral conflict. |
| P0[25]/RD1 | CAN1 receiver input | Differential input for CAN bus termination; requires external transceiver (e.g., TJA1050) for physical layer compliance. |
| P0[27]–P0[30]/AIN0–AIN3 | ADC analog inputs | Four dedicated 10-bit analog inputs; 0–3 V full-scale range; internally connected - no routing required in PCB layout. |
| P1[26]/RTCK | Returned test clock | Enables adaptive JTAG synchronization during variable-frequency debugging; pulled up internally. |
| VDD(1V8), VSS | Core power/ground | Separate 1.8 V core rail decoupling required; noise-sensitive analog sections demand local ceramic bypassing near VDDA(1V8)/VSSA. |
Key Features
| Feature | Design Value |
|---|---|
| Fast GPIO Registers | Relocated to ARM Local Bus; enables port pin toggling up to 3.5× faster than legacy LPC2000 - critical for bit-banged protocols or high-speed sensor polling. |
| Dedicated ADC Result Registers | One register per AIN channel; eliminates read-modify-write cycles during interrupt handling - reduces latency in closed-loop control systems. |
| Fractional Baud Rate Generator | Supports precise UART0/1 baud rates (e.g., 115200, 921600) across wide clock ranges without external crystal tuning. |
| Embedded Trace Macrocell (ETM) | Non-intrusive real-time instruction trace; captures program flow without halting CPU - essential for debugging hard real-time deadlines. |

FAQ
What is the maximum operating frequency of the LPC2109FBD64/01?
The LPC2109FBD64/01 achieves a maximum CPU clock frequency of 60 MHz using its on-chip programmable Phase-Locked Loop (PLL) with 100 µs settling time. This frequency is sustained by the 128-bit wide flash interface and accelerator, enabling deterministic real-time execution in automotive and industrial control applications where the LPC2109FBD64/01 serves as the primary system controller.
Does the LPC2109FBD64/01 support In-System Programming (ISP)?
Yes, the LPC2109FBD64/01 supports In-System Programming via its UART0 interface using the on-chip bootloader. Flash programming takes 1 ms per 512-byte line, and sector or full-chip erase completes in 400 ms. This capability allows firmware updates in deployed systems without removing the LPC2109FBD64/01 from the PCB, making it ideal for remote maintenance in automotive and industrial environments.
How many CAN interfaces does the LPC2109FBD64/01 include?
The LPC2109FBD64/01 includes one CAN 2.0B-compliant controller, distinct from the LPC2119FBD64/01 and LPC2129FBD64/01 which each feature two CAN channels. This single CAN interface supports data rates up to 1 Mbit/s and integrates advanced acceptance filters for selective message reception - sufficient for body control networks or point-to-point industrial communication where the LPC2109FBD64/01 is deployed.
What distinguishes the /01 suffix in LPC2109FBD64/01?
The /01 suffix denotes enhanced peripheral features including Fast GPIO registers (3.5× faster pin toggling), dedicated ADC result registers per channel, 5 V-tolerant ADC pads in digital I/O mode, and SSP serial controller support - all absent in /00 variants. These enhancements directly improve real-time responsiveness and reduce interrupt latency in applications relying on the LPC2109FBD64/01 for sensor acquisition or protocol bridging.
What power supply rails does the LPC2109FBD64/01 require?
The LPC2109FBD64/01 requires two independent power supplies: a 1.65–1.95 V (nominal 1.8 V ±0.15 V) core rail (VDD(1V8)) and a 3.0–3.6 V (nominal 3.3 V ±10 %) I/O rail (VDD(3V3)). Analog sections use isolated VDDA(1V8) and VDDA(3V3) supplies, while VSSA and VSSA(PLL) provide dedicated analog grounds - ensuring noise immunity for the 10-bit ADC and PLL circuits within the LPC2109FBD64/01.
