Product details
Overview
LPC2194JBD64,151 from NXP Semiconductors (formerly Philips) is a 16/32-bit ARM7TDMI-S microcontroller in LQFP64 package, featuring 256 kB on-chip Flash, 16 kB SRAM, four independent CAN interfaces, and a 4-channel 10-bit ADC with 2.44 µs conversion time. It operates at up to 60 MHz via on-chip PLL and supports −40 °C to +105 °C industrial temperature range - designed for automotive CAN gateways and fault-tolerant industrial control systems.
For engineers reviewing the LPC2194JBD64,151 datasheet, LPC2194JBD64,151 pinout, LPC2194JBD64,151 application, or LPC2194JBD64,151 equivalent, key selection criteria include multi-CAN channel count, 10-bit ADC sampling performance, ARM7 real-time debug support (EmbeddedICE-RT/ETM), and dual-power domain operation (1.8 V core / 3.3 V I/O with 5 V tolerant pins).
Technical Context
The LPC2194JBD64,151 implements an ARM7TDMI-S CPU with Thumb instruction set support, enabling 32-bit performance at reduced code size. Its 128-bit wide memory interface and accelerator architecture sustain full 60 MHz execution speed while supporting both ARM and Thumb modes.
Four independent CAN controllers integrate advanced acceptance filters and share dedicated interrupt channels (VIC slots 19–27). The 10-bit ADC supports burst mode, external trigger, and timer-match-triggered conversions across four analog inputs (AIN0–AIN3), all referenced to 0–3 V range.
Key Specifications

|---|---|
| CPU Core | ARM7TDMI-S 32-bit RISC processor with Thumb mode; enables high code density and deterministic real-time interrupt response. |
| Max Clock Speed | 60 MHz via programmable on-chip PLL; eliminates need for external clock generator in most timing-critical applications. |
| Memory | 256 kB ISP/IAP Flash (248 kB user-available with bootloader), 16 kB SRAM; supports field firmware updates without external programmer. |
| CAN Interfaces | 4 independent CAN 2.0B-compliant controllers with configurable acceptance filters; enables multi-bus bridging (e.g., CAN gateway between 125 kbps and 500 kbps subnets). |
| ADC | 4-channel 10-bit successive approximation ADC; 2.44 µs conversion time supports >400 kSPS throughput for sensor monitoring. |
| I/O & Power | 46 GPIO pins (5 V tolerant), dual supply: 1.65–1.95 V core (V18/V18A), 3.0–3.6 V I/O (V3/V3A); allows mixed-voltage system integration. |
| Debug Interface | EmbeddedICE-RT and Embedded Trace Macrocell (ETM); enables real-time instruction tracing and non-intrusive debugging without halting CPU. |

Yes, the LPC2194JBD64,151 supports In-System Programming (ISP) via UART0 or UART1 using the on-chip boot-loader. Flash programming occurs at 1 ms per 512-byte line, and sector or full-chip erase completes in 400 ms - enabling field firmware updates without removing the device from the target board.
How many CAN interfaces does the LPC2194JBD64,151 provide, and are they independent?
The LPC2194JBD64,151 integrates four fully independent CAN 2.0B-compliant controllers, each with dedicated message RAM, acceptance filter units, and separate interrupt assignments (VIC channels 19–27). They operate concurrently without resource contention, making LPC2194JBD64,151 ideal for multi-bus bridging and gateway applications.
What is the ADC resolution and conversion speed of the LPC2194JBD64,151?
The LPC2194JBD64,151 features a 10-bit successive approximation ADC with four input channels (AIN0–AIN3). Its minimum conversion time is 2.44 µs, enabling sustained sampling rates exceeding 400 kSPS - verified under 0–3 V input range and supported by burst mode and external trigger capabilities.
