MC12311: Sub-1 GHz RF and 8-bit HCS08 MCU with 32KB Flash, 2KB RAM

Overview

Please note that this product 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
