LPC800 Mikrokontroler ARM Dengan Kemasan DIP

Awal tahun 2012 lalu NXP telah mengeluarkan mikroprosesor ARM Cortex M0 dengan kemasan DIP (Dual In Line Package), yaitu tipe LPC1114FN28.

Model ini diikuti oleh model berikutnya yaitu LPC800 yang dikeluarkan pada akhir 2012. LPC800 ini juga dari keluarga ARM Cortex-M0.

NXP juga menyelenggarakan kompetisi terkait dengan produk baru ini, yaitu LPC800 Simplicity Challenge. Kompetisi ini nampaknya bertujuan mempromosikan keunggulan LPC800 yaitu kesederhanaan dan low power.

Sejauh ini baru NXP yang membuat prosesor ARM dengan kemasan DIP, yaitu LPC810 dengan kemasan 8 pin DIP dari keluarga LPC800 dan LPC1114FN28 dengan kemasan 28 pin DIP dari keluarga LPC1100.

Menurut situs toko komponen online Element 14 (http://sg.element14.com), komponen ini harganya per unit adalah SGD 1,28 atau sekitar Rp 10.100,- saja. Lumayan murah, mengingat mikrokontroler Atmel AT89S51 di Bandung dijual sekitar Rp 12.500,- saja.

Berikut ini spesifikasi dari LPC800 tersebut:

    • System tick timer
    • Serial Wire Debug (SWD) and JTAG boundary scan modes supported
    • Micro Trace Buffer (MTB) supported
  • Memory:
    • 4 kB on-chip flash programming memory
    • 1 kB SRAM
  • Boot ROM API support:
    • Boot loader
    • USART drivers
    • I²C drivers
    • Power profiles
    • Flash In-Application Programming (IAP) and In-System Programming (ISP)
  • Digital peripherals:
    • High-speed GPIO interface connected to the ARM Cortex-M0+ IO bus with 6 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors
    • GPIO interrupt generation capability with boolean pattern-matching feature on eight GPIO inputs
    • Switch matrix for flexible configuration of each I/O pin function
    • State Configurable Timer (SCT) with input and output functions (including capture and match) assigned to pins through the switch matrix
    • Multiple-channel multi-rate timer for repetitive interrupt generation at up to four programmable, fixed rates
    • Self Wake-up Timer (WKT) clocked from either the IRC or a low-power, low-frequency internal oscillator
    • CRC engine
    • Windowed Watchdog timer
  • Analog peripherals:
    • Comparator with external voltage reference with pin functions assigned or enabled through the switch matrix
  • Serial interfaces:
    • Two USART interfaces with pin functions assigned through the switch matrix
    • One SPI controller with pin functions assigned through the switch matrix
    • One I²C-bus interface with pin functions assigned through the switch matrix
  • Clock generation:
    • 12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as a system clock
    • Crystal oscillator with an operating range of 1 MHz to 25 MHz
    • Programmable watchdog oscillator with a frequency range of 9.4 kHz to 2.3 MHz
    • 10 kHz low-power oscillator for the WKT
    • PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency crystal. May be run from the system oscillator, the external clock input CLKIN, or the internal RC oscillator
    • Clock output function with divider that can reflect the crystal oscillator, the main clock, the IRC, or the watchdog oscillator
  • Power control:
    • Integrated PMU (Power Management Unit) to minimize power consumption
    • Reduced power modes: Sleep mode, Deep-sleep mode, Power-down mode, and Deep power-down mode
    • Power-On Reset (POR)
    • Brownout detect
  • Unique device serial number for identification
  • Single power supply
  • Available as DIP8 package
