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:

LPC1114FN28 Mikroprosesor ARM Dengan Kemasan Dual In Line Package (DIP)

ARM adalah salah satu arsitektur prosesor 32 bit yang banyak dipakai akhir-akhir ini. Prosesor keluarga ARM ini diproduksi oleh berbagai produsen mikroprosesor dengan berbagai kemasan yang berbeda. Di antara sekian banyak model prosesor ARM, setahu saya sampai saat ini hanya ada 1 model saja yang menggunakan kemasan DIP (Dual Inline Package), yaitu tipe LPC1114FN28 dari NXP. Adanya kemasan DIP ini tentu saja memudahkan para hobbiyst yang tidak sanggup menyolder kemasan SMD ataupun yang mau mencoba dulu di breadboard.

Menurut seorang rekan yang bekerja di pabrik mikroprosesor, industri lebih menyukai kemasan SMD karena (a) lebih kecil dan (b) perlu material plastik lebih sedikit,  sehingga dengan kemasan SMD ini diperoleh perangkat yang lebih kecil dan harga yang lebih murah. Bagi orang yang terbiasa menggunakan kemasan DIP seperti yang banyak di ATMega, adanya ARM dengan kemasan DIP ini tentunya membuka peluang mengoprek ARM tanpa perlu belajar menyolder komponen SMD.
