应用

The OM6228 is a member of the low-cost, high-performance family of intelligent 2.4 GHz RF transceivers with embedded microcontrollers. The OM6228 is optimized to provide a single chip solution for Ultra Low Power (ULP) wireless applications. The combination of processing power, memory, low power oscillators, real-time counter and a range of power saving modes provides an ideal platform for implementation of RF protocols. Benefits of using OM6228 include tighter protocol timing, security, lower power consumption and improved co-existence performance.

Features of the OM6228 include:

► Fast 8-bit microcontroller:

♦ Intel MCS 51 compliant instruction set

♦ Reduced instruction cycle time, up to 12 times compared to legacy 8051

►Memory:

♦ Program memory: 16 kB of OTP memory with security features

♦ Internal RAM: 256Byte

►A number of on-chip hardware resources are available through programmable multi-purpose input/output pins:

♦ 32 GPIO

♦ Full duplex serial port

♦ 6 PWMs

♦ External interrupts

►High performance 2.4 GHz RF transceiver

♦ True single chip GFSK/FSK transceiver

♦ Enhanced Shock-Burst™ link layer support in HW:

• Packet assembly/disassembly

• Address and CRC computation

• Auto ACK and retransmit

♦ On the air data rate 1 Mbps or 2 Mbps

♦ 125 RF channels operation, with 79 (2.402 GHz –2.480 GHz) channels within 2.400–2.4835 GHz

♦ Short switching time enable frequency hopping

►System reset and power supply monitoring:

♦ On-chip power-on and brown-out reset

♦ Watchdog timer reset

♦ Power-fail comparator with programmable threshold and interrupt to MCU

►On-chip timers:

♦ Two16-bit timers/counters operating at the system clock (sources from the 16 MHz on-chip oscillators)

• Timer 0, Timer 1 are compatible to standard 8051

♦ One 16-bit timer/counter operating at the low frequency clock (32kHz)

►On-chip oscillators:

♦ 16 MHz crystal oscillator XOSC16M

♦ 32kHz RC-oscillator RCOSC32K

►Power management function:

♦ Low power design supporting fully static stop/standby

♦ Programmable MCU clock frequency from 125 kHz to 16 MHz

♦ On chip voltage regulators supporting low power mode

♦ Watchdog and wakeup functionality running in low power mode

► Wireless keyboard
