Sub-1 GHz RF and 8-bit HCS08 MCU with 32KB Flash, 2KB RAM

MC12311
  • Not Recommended for New Designs
  • This page contains information on a product that is not recommended for new designs.

Powered by the low-power S08QE 8-bit microcontroller, the MC12311 embeds a rich set of peripherals with a high-performance sub-1 GHz radio, capable of operating over a wide frequency range including 315, 433, 470, 868, 915, 928 and 960 MHz in the license-free industrial, scientific and medical (ISM) frequency bands. This configuration allows users to minimize the use of external components.

Software Solutions

  • Our MC12311 simple media access controller (SMAC) is a simple ANSI C-based code stack available as sample source code. It is used for developing proprietary RF wireless applications using a sub-1 GHz transceiver. The MC12311 SMAC was built to enable the flexibility of the MC12311 integrated circuit (IC). The MC12311 SMAC is incorporated into the BeeKit® Wireless Connectivity Toolkit, which makes it easier for users to employ and customize MC12311 SMAC
  • Our MC12311 radio utility application provides a way to interact with the transceiver based on SMAC embedded applications. The radio utility application allows for complete configuration of the radio as well as basic transmitter and receiver tests
  • IEEE® 802.15.4 MAC with custom PHY layer: NXP® has developed a subset of the 802.15.4 PHY/MAC that fits into the internal flash memory of the MC12311. It supports the G-FSK modulation with multiple frequencies, data rates and channels
  • NXP provides support for wireless M-Bus through our partner AMiHO. NXP provides an evaluation version of wireless M-Bus and a full version can be purchased through AMiHO
