MC908EY16AKFJE

The MC68HC908EY16A is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). The information contained in this document pertains to the MC68HC908EY8A with the exceptions noted in Appendix A MC68HC908EY8A. All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.

The features of MC908EY16AKFJE can be summarized as (1)high-performance M68HC08 architecture optimized for C-compilers; (2)fully upward-compatible object code with M6805, M146805, and M68HC05 Families; (3)8-MHz internal bus frequency at 5V; (4)internal oscillator requiring no external components: software selectable bus frequencies 25 percent accuracy with a trimming capability of better than 1 percent clock monitor option to allow use of external clock source or external crystal/ceramic resonator; (5)15,872 bytes of on-chip FLASH memory with in-circuit programming; (6)FLASH program memory security(1); (7)512 bytes of on-chip random-access memory (RAM); (8)low voltage inhibit (LVI) module; (9)internal clock generator module (ICG); (10)two 16-bit, 2-channel timer (TIMA and TIMB) interface modules with selectable input capture, output compare, and pulse-width modulation (PWM) capability on each channel; (11)8-channel, 10-bit successive approximation analog-to-digital converter (ADC); (12)enhanced serial communications interface module (ESCI) for local interconnect network (LIN) connectivity; (13)serial peripheral interface (SPI); (14)timebase module (TBM); (15)5-bit keyboard wakeup port with software selectable rising or falling edge detect, as well as high- or low-level detection Programmable for rising/falling edge or high/low level detection; (16)24 general-purpose input/output (I/O) pins; (17)external asynchronous interrupt pin with internal pullup (IRQ); (18)system protection features: optional computer operating properly (COP) reset Illegal opcode detection with reset Illegal address detection with reset; (19) 32-pin quad flat pack (QFP) package; (20)low-power design; fully static with stop and wait modes; (21)internal pullups on IRQ and RST to reduce customer system cost; (22)standard low-power modes of operation: wait mode stop mode; (23)Master reset pin (RST) and power-on reset (POR); (24)BREAK module (BRK) to allow single breakpoint setting during in-circuit debugging; (25)Higher current source capability on nine port lines for LED drive (PTA6/SS, PTA5/SPSCK, PTA4/KBD4, PTA3/KBD3/RxD, PTA2/KBD2/TxD, PTA1/KBD1, PTA0/KBD0, PTC1/MOSI, and PTC0/MISO).

The absolute maximum ratings of MC908EY16AKFJE are (1)supply voltage VDD: 0.3 to +6.0 V; (2)input voltage VIn: VSS 0.3 to VDD +0.3 V; (3)Maximum current per pin excluding VDD, VSS, and PTA0PTA6 and PTC0-PTC1 I : ±15 mA; (4)Maximum current for pins PTA0PTA6 and PTC0-PTC1 IPTA0IPTA6, IPTC0IPTC1: ±25 mA; (5)maximum current out of VSS IMVSS: 100 mA; (6)maximum current into VDD IMVDD: 100 mA; (7)storage temperature TSTG: 55 to +150 °C.
