1 / 23 page 1/23 STLC2500 May 2004 This is preliminary information on a new product now in development. Details are subject to change without notice. 1FEATURES ■ Bluetooth™ specification compliance: V1.1 and V1.2 ■ Ericsson Licensing Technology Baseband Core (EBC) ■ Point-to-point, point-to-multi-point (up to 7 slaves) and scatternet capability ■ Asynchronous Connection Oriented (ACL) logical transport link ■ Synchronous Connection Oriented (SCO) link: 2 simultaneous SCO channels ■ Support Pitch-Period Error Concealment (PPEC) – Improves speech quality in the vicinity of in- terference – Improves coexistence with WLAN – Works at receiver, no Bluetooth implication ■ Adaptive Frequency Hopping (AFH): hopping kernel, channel assessment as Master and as Slave ■ Faster Connection: Interlaced scan for Page and Inquiry scan, first FHS without random back off, RSSI used to limit range ■ Extended SCO (eSCO) links ■ HW support for packet types – ACL: DM1, 3, 5 and DH1, 3, 5 – SCO: HV1, 3 and DV – eSCO: EV3, 5 ■ Clock support – System clock input (digital or sine wave) at 13, 26, 19.2 or 38.4 MHz – LPO clock input at 3.2, 16.384, 32 or 32.768 kHz ■ ARM7TDMI CPU –32-bit Core – AMBA (AHB-APB) bus configuration ■ Patch RAM capability ■ Memory organization – On chip RAM, including provision for patches – On chip ROM, preloaded with SW up to HCI ■ Communication interfaces –Fast UART – PCM interface – 4 programmable GPIOs – External interrupts possible through the GPIOs – Fast master I2C interface ■ Efficient support for WLAN coexistence in collocated scenario ■ Ciphering support up to 128 bits key ■ Software support – Lower level stack (up to HCI) – HCI Transport Layer: H4 (including propri- etary extensions) – HCI proprietary commands (e.g. peripherals control) – Single HCI command for patch/upgrade download ■ Single power supply with internal regulators for core voltage generation ■ Supports 1.65 to 2.85 Volts IO systems ■ Total number of external components limited to 7 (6 decoupling capacitors and 1 filter) thanks to: – Fully integrated synthesizer (VCO and loop filter) – Integrated antenna switch – Low IF receiver ■ Auto calibration (VCO, Filters) ■ No need for calibration of the RF part ■ Timer and watchdog ■ Power class 2 compatible ■ Ultra low power architecture with 3 different low power levels: – Sleep Mode – Deep Sleep Mode – Complete Power Down Mode ■ Software Initiated Low Power Mode ■ Dual Wake-up mechanism: initiated either by the Host or by the Bluetooth device ■ Standard TFBGA-84 pins package 2DESCRIPTION The STLC2500 is a single chip ROM-based Blue- tooth solution implemented in 0.13 m ultra low power, low leakage CMOS technology for applica- tions requiring integration up to HCI level. Patch RAM is available enabling multiple patches/up- grades. The STLC2500's main interfaces are UART for HCI transport, PCM for voice and GPIOs for con- trol purposes. The Radio is designed for the single chip requirement and for drastic power consump- tion reduction. PRELIMINARY DATA BLUETOOTH™ SINGLE CHIP REV. 1 Figure 1. Package Table 1.
